How to Preserve Yellow Wax Beans (Flash Freezing)
The beans are really growing at this point in the season, so I am starting to put some away for the winter. For beans I really like to blanch and freeze them. It is the easiest method that preserves the most taste and nutrients. You really should blanch your beans before freezing them because it stops the enzymes which cause the loss of flavor and nutrients. See below for instructions.
1. Wash your beans.
2. Cut the ends off.
3. Bring a large pot of water to a rolling boil.
4. Place your beans into the pot. The pot will stop boiling, but when it starts to boil again, leave the beans in for 3 minutes while boiling.
5. Dump beans out into a colander, then immediately into an ice water bath for 3 minutes.
6. Put the beans back into the colander, and dry them with a clean towel quickly (They don’t need to be perfectly dry, just dry enough to be vacuum packed).
7. Place your beans into a vacuum pack freeze and steam bag, and vacuum pack, then place in the freezer. You can also use freezer zip lock bags. These will not keep the beans quite as fresh, and you will want to remove the air as best you can with a straw before placing in the freezer.
