How to take a break from yogurt
So you need to take a break from making yogurt or you would like to switch varieties? Let’s take a look at the different options.
Short term storage: Freeze the yogurt into ice cube trays. Once frozen, place in a freezer safe bag and store in the freezer for up to 3 months. If reactivating closer to the 3 month mark use double the amount of yogurt starter per cup of milk. An ice cube try is a perfect way to store a tablespoon of yogurt. You can roll the yogurt cubes in powdered milk to help avoid freezer burn. Its easy to activate the yogurt starter when you need to. Just take out the desired amount of starter and defrost slowly in the refrigerator. Add the yogurt starter into fresh milk and give it a stir. Now you’re in business!
Long term storage: Spread a very thin layer of yogurt on a piece of unbleached parchment paper and let air dry for 2-3 days until completely dry. Flake the yogurt off the parchment paper into a freezer safe bag and add just a bit of powdered milk. Store in the freezer for up to 6 months. Again, the yogurt cultures can and will store longer but for viability sake try to stick to six months. If reactivating closer to six months use double the amount of yogurt starter per cup of milk.
Either way you decide to store your yogurt starter make sure to freeze the most recent/freshest batch of yogurt.
