Some of my fondest memories as a child was "helping" Gram to put up green beans.
According to Wikipedia: "Green beans, also known as French beans (British English), string beans in the northeastern and western United States, snap beans or squeaky beans, are the unripe fruit of specific cultivated varieties of the common bean (Phaseolus vulgaris)". The are easy to freeze for a taste of summer in the middle of winter.
No matter what color or what you call them, I love them straight out of the garden.
Availability may vary by variety and with weather conditions.
Store unwashed fresh beans pods in a plastic bag kept in the refrigerator crisper. Whole beans stored this way should keep for about seven days.
Frozen in an air tight container for up to 6 months.
Just prior to using the green beans, wash them under running water. Remove both ends of the beans by either snapping them off or cutting them with a knife.
Steam them for about 5 mintues.
Lightly saute them with mushrooms.
Blanch for 2-3 minutes, then freeze for up to 6 months.
Don't forget about pickling.
