I had a huge garden at the back of our house in Texas. For the past 3 years I planted different kinds of veggies and I harvested a lot too. For now, I'm going to post the string beans and my bitter gourd from my garden last year. My veggies yielded a lot so what I did, I cut the string beans and blanched it. After that I put it in a ziploc bag and put it in the freezer. It lasted a few months. I didn't do that it with the bitter gourd though. I like to cook it fresh from the garden so it won't taste so biter. Whenever I pick some I cooked it right away with ground beef, tomatoes and eggs. My American husband love it. He said it tasted so good.
