I’m still trying to find a good chilli sauce that doesn’t have sugar or
onion in it (Garlic is OK, it doesn’t make me ill for some reason), and
is easily available in the UK. If I get enough lemon drop chillies this
year I willl try to make my own sauce from them.
I’ve never worked with lemon drops, but I highly recommend the “do it yourself” approach if you want a good hot sauce. It doesn’t take very many ingredients. peppers, garlic, salt, vinegar. Maybe smoke a batch of the peppers and add them in with fresh ones, or try dried of various maturities. They all contribute different flavors. Possibly try one of the other polar solvents used in cooking in place of the vinegar, or use an oil.
I’m Not giving up any of my recipes here, but it’s a fun area of cooking to play with and properly canned / bottled hot sauces will last a long time.
I also realize the UK might not have the best climate for growing hot peppers, so you might have to import. I can’t say what kind of results you’d get with a hothouse there, but also maybe an option.
