After veggies are prepped, the next step is to bring a large bowl of water to boiling, in the microwave.
I added the asparagus to the hot water and blanched (cooked) it on High for 3 minutes. This process is important because it stops the enzymes that cause food to spoil.
Also have ready, a bowl of ice water. Make sure the bowls you use are stoneware or other ceramics that will tolerate the sudden change of temperature for this technique.
Use a slotted spoon and lift the veggies out of the hot water and into the ice water to stop the cooking process.
Let the veggies chill for several minutes to be sure they are cold all the way through.
After cooling, lift the vegetables out and drain them in a colander to remove excess water.
Label and date are a good idea if you do very many packages.
You can read on line for suggestions on blanching and freezing other vegetables. If you have the freezer space to do this, you can count on having just what you need to make a favorite recipe.
P. S. Some of the fresh asparagus is going into tonight's dinner. Watch for that recipe later.
