Some foods, you can’t buy in a shop, without packaging. Peas are either sold in plastic tubs or frozen in a bag. My farm box don’t sell peas.
Sometimes they sell peas in Real Foods. They only come whole, in a pod. Its kinda fun to pop them yourself but a bit disappointing, that you pay so much for the empty pod.
If you need a large amount of peas, you could try to substitute with dries peas, if your recipe allows.
I’m glad, my daughter enjoys helping me in the kitchen and she really enjoyed, popping all the peas out of the pods.
