Autumn Foraging: Apples

In my neighbor’s garden there is an old apple tree. The tree and the garden is in need of care. It always hurts my heart when I see fruit of any kind fall to the ground before anyone even thinks of taking care of them. As nobody actually lives next door I think its ok to pick them. So I went over there to have a look. The apples didn’t look that great and they would probably be terrible in most things, I thought. I took a bite and smiled. It was a crisp bite and the taste was sweet and sour at the same time. This abandoned tree was in fact a Granny Smith or at least something very close to it. Granny Smith may not be my absolute favorite but an apple like this is excellent in an apple tart or a nutty manchego salad.

Apples in general are very useful in cooking, for both savory or sweet dishes. A chicken for example is really flavorful when roasted whole filled with apples and prunes. Different kinds of preserves such as apple compote, apple butter and apple chutney are fantastic treats that can be served with many different things, such as a sweet flavor in oatmeal, as a side to meat or together with cheese on bread. While growing up I remember having only apple compote with cold milk as an afternoon snack.

Then there are endless amazing cakes and pies that can be baked with apples. There is of course always the classic Tarte Tartine that was created by two sisters after a successful accident in the kitchen. A more unusual apple pie is the south Swedish version (Skånsk Äpplekaka) that is made with rye bread crumbs. It may sound strange but its absolutely delicious served with vanilla sauce.

If you have a lots of apples you should really consider making your own apple juice or cider. If my neighbor’s tree would give me more apples, I would definitively brew hard apple cider. Sandor Ellix Katz says, in his book “wild fermentation”, to brew apple cider is one of the simplest alcohol fermentation you can make. You just need fresh good quality apple juice (preferably juiced by yourself), a jug, a cheese cloth and a rubber band. He calls it Spontaneous Cider.

Last year I got really inspired by Joanna at Zeb Bakes when she made apple cider vinegar with the scraps and pieces that were left over after making apple cake. I think it’s really clever to use something that normally would be thrown away. Joanna’s vinegar was inspired by Carl Legge‘s experiments which he describes very well in his post Fermenting Revolution 2 – Apple cider vinegar. The below recipe is pretty much the same as Carl’s formula (Sandor Katz suggests less sugar in his book).

I think my neighbor’s Granny Smith are perfect for this recipe.

Granny Smith Cider Vinegar

  • ½ cup (about 120 ml) sugar (I used half regular sugar and half brown)
  • 4 ¼ cup (one liter) water
  • 6-12 small Granny Smith apples* (more or less if you are using scraps or whole apples)

Heat up the water together with the sugar. When the sugar has dissolved into the water take off the heat and let cool. This is important as hot liquid will not let the natural yeast start the process. During this time you can prepare the apples. I used whole apples, which I rinsed and cut into one inch (2-3 cm) pieces. But you can use leftover bits and pieces as well. Place the apples in a large glass jar or other suitable container. It’s good if the jar has a wide opening, according to Sandor Katz a larger exposure to air helps the process.

When the sugar solution is cool enough (about room temperature) pour it over the apple pieces. Place a plate on top to weigh down the apples (I took a bowl and a mortar). Place the container in a warm place. To avoid flies etc cover with a cheesecloth or kitchen towel (fastened by a rubber band). Stir and taste the apples every day. (After about 3 days I could see small bubbles and the flavor was sweet and fizzy. This as a good sign, the fermenting process is doing what it should do).

After 7-10 days, the apples have done their job and you will need to strain them through a sieve. Pour back into the jar and let stand for another 7-14 days. Continue to taste your batch regularly. It will soon start to taste more like vinegar than cider. When you are happy with the flavor, strain the liquid again and pour the liquid into sterilized bottles and seal them properly. The film that will be created on top is called “Mother of Vinegar” that can be used as a starter for your next vinegar.


* You can of course use any other kind of apple in this recipe. You can also make vinegar with other kinds of fruit and berries. Sandor Katz mentions in his book that almost any fruit scraps and peels etc can be used for making vinegar. He suggests pineapple, grapes or even overripe bananas.

How to Make Kefir

My temporary landlord Russell Busch, who is also a good friend, just introduced me to kefir making. Kefir is a fermented milk drink that contains plenty of healthy probiotics. To make kefir from milk you need kefir grains which are a live and active culture of yeast and bacteria.

Kefir is a very common drink in Eastern Europe and the Nordic countries. I grew up with it and if I remember correctly, the Swedish kefir is thicker, more sour and has a slightly carbonated feel to it. Swedes often eat kefir (with a spoon) together with muesli, cornflakes, fruit or just with sugar and cinnamon. I like my kefir best just plain with fresh fruit or berries. Others prefer making smoothies with frozen berries and fruits as it takes off some of the strong sour flavor. Luckily Kefir has become increasungly common here in the US.

The kefir making process is super easy and you don’t really need to do much as the kefir grains do most of the work.

to make kefir you will need:

  • kefir grains (which you order online here or here or somewhere else)
  • organic whole milk from cow, sheep or goat
  • glass jar
  • small piece of cheese cloth + rubber band (or similar)
  • wood or plastic spoon/ spatula
  • fine mesh plastic strainer (or stainless steel)

note: no metal such as aluminum etc can be used as it will react with the kefir grains. Although, for some reason stainless steel seems to be OK.

Place the new kefir grains in a clean glass jar (about two tablespoons). Pour about 1 cup organic whole milk over the grains. Cover with the cheesecloth and fasten it with a rubber band to avoid flies (I actually just use a plastic lid that is just placed on top). Leave the jar on the counter in room temperature away from any sun.

When the kefir has got thicker the kefir is probably done. It should smell pleasantly and have a mild sour taste. At this stage you will have a drinkable kefir. If it stays longer the kefir will start to separate the curdled milk from the whey. Don’t worry, the kefir is still fine, however it will be slightly thicker and have a richer taste. A longer fermentation will also create more probiotics and less lactose. The fermentation will take about 12-36 hours.

When you think you are ready, give the jar a shake and drain it through the plastic strainer to separate the kefir from the grains. It’s important to be gentle with the grains so don’t press them too hard. The kefir grains don’t have to be totally clean from curds for the next batch. The ready-made kefir can be stored in the fridge, preferably in a glass container. It will keep fresh for awhile. If you think the kefir is too loose you can strain it to reduce some of the whey. Leftover whey can be used for many things (see below).

next batch
Prepare the next batch by placing the strained kefir grains into a clean glass jar. This time you should add a little more milk and the fermenting process will probably go faster as the grains have grown larger and become more active.

The more kefir you make the bigger the grains will grow, you will therefore need to adjust the amount of milk depending on their size. At some point you need to split the grains up as there is a limit on how much kefir you can make. I suggest giving some grains to a friend or start making other things with it. You can, for example, make kefir drinks by using almond, soy or coconut milk instead of regular milk. In this kind of process the grains will not grow and therefore not last as long. I haven’t tried it yet but my landlord makes coconut kefir drinks daily.

what to do with the kefir
There are many other things you can do with the kefir if you don’t just want to drink or eat it. Kefir is excellent in dips, dressings, cakes and bread. It can also be used instead of yeast when baking bread or at least that’s what I’ve heard.

Recently I made my own cream cheese or rather fresh cheese by straining the kefir from the whey through a clean kitchen towel or several layers of cheese cloth (takes about 24 hours). This creamy cheese can be served plain or flavored with fresh herbs, garlic or anything you like. Its also great to make pierogi leniwe (Polish lazy pierogi).

You can do many things with the whey such as ferment vegetables, sauerkraut (cabbage) and when diluted 5 times with water it can be used as a fertilizer for your plants. For about a week I collected the leftover whey to make ricotta. I was amazed how well it worked out as the whey just looks like cloudy water.

storing the kefir grains
At some point you may want to have a break in your kefir making and it’s actually possible to store the kefir grains with some milk in your fridge. Just feed them with new fresh milk every now and again. When you start again the grains may not be as active as before the break, so you probably have to start again with just a small amount of milk.
