I bought 5 lbs of Bloody Butcher Red Corn Kernels to make homemade tortillas. The corn needs to go through the nixtamalization process of cooking in lime water (calcium hydroxide) before grinding the corn into masa. I have tried twice and for some reason this corn takes a lot longer to simmer than the 40 minutes called for in the recipes, and the results are not uniform. Some kernels are al dente and some are not. I will try again with a different recipe that calls for less boiling time and longer soaking time, but I have a feeling this corn may be stale. Hope not. I gave the product 3 stars for this reason. The customer service and quality of the order fulfillment (packaging, quick no-hassel delivery) is 5-star, so the average is 4!
