The Pantry Staple That Can Change Your Cooking
There are many sources mentioned between the article and the comments , this is one of them
One of the comments says “Fire Tongue Farms grows peppers in three different micro-climates in California to get the best results.”
From the website “about us”
“…mild varieties grow along the coast in Santa Cruz spending part of the summer maturing in the cool coastal fog, our medium peppers grow in the Mediterranean climate of the San Juan Valley, while our hottest cultivars ripen in the hot inland temps of the Capay Valley.”
That sounds mostly right.
