Please don't judge real Serranos based on Walmart "Serranos", which are definitely hybrids with tame heat for the average American consumer. And if you think those are good (or bad) wait til you try the real thing! Grow the real ones like Tampiqueno, Huasteco, or a generic heirloom/OP variety, although they are significantly smaller, you will surely discover a significant difference in flavor and heat. I can no longer buy Jalapenos and Serranos from large chain stores anymore, I became jaded from eating really delicious and hot ones grown from the garden or bought at a local tienda Mexicana. Just my 2 cents, take it or leave it....
