@hipsterelectronoh serranos are great. they look a lot like jalapeños, but a bit smaller and less likely to be curved. thinner walls and seeds and everything. easy to mistake for a baby jalapeno if you don't know about them.flavor-wise, they're less bell peppery and earthy than jalapeno. brighter/sharper/fresher, if that makes sense. compliments lime really well. other than latin american cuisines, only common usage I know of is that a lot of sushi restaurants in the US will pair them with yellowtail fish... not sure how that came about, but it works haha! i'm able to find them in most grocery stores.heat is between jalapeño and habanero, which can be a wide range. def a very notable increase from jals. i can usually just chomp into a raw jalapeño no problem, but more often not with serranos.
