Has anyone used this method for freezing red peppers? This info is from the University of Nebraska at Lincoln:
Freezing Sweet or Bell and Hot Peppers
Alice Henneman, MS, RD, UNL Lancaster County Extension
Peppers are one of those foods you can quickly freeze raw without blanching them first. Thawed, raw peppers still retain some crispness and can be used in cooked dishes or raw in uncooked dishes.
Bell or Sweet Peppers (Green, Red, Yellow, Orange, Purple)
Select crisp, tender peppers.
Cut out stems and cut peppers in half.
Remove seeds and membrane -- save time by using a melon baller or the tip of a spoon to scrape out seeds and membrane.
Cut peppers into strips, dice or slice, depending on how you plan to use them.
Freeze peppers in a single layer on a cookie sheet with sides, about an hour or longer until frozen. This method is often referred to as "tray freezing."
Transfer to a "freezer" bag when frozen, excluding as much air as possible from the bag. The peppers will remain separated for ease of use in measuring out for recipes.
Pour out the amount of frozen peppers needed, reseal the bag and return to the freezer.
