Hi Guys, Thanks for all input. I appreciate what you are all saying re the blended or mono, is personal preference depending upon what you want to achieve. (At this moment this is my first go at fermenting so all I want to do is make some hot sauce!)
I haven't got as far as refining what taste I want to achieve...yet.
(I have been growing for a few years now and have refined what we will grow going forward, which is predominantly Bhut's (For freezing / drying and cooking, especially Indian curry's as the taste and heat are perfect), Cayennes (for freezing / cooking) then for Caribbean style sauces, jerk and drying, a few Jonah's, Reapers and a Bubblegum as I believe that the fruity taste of these is given more to the Caribbean sauces).
I did some mixed variety pickled chillies last year that came out great.
I may try a blended and a mono sauce with maybe some garlic (in my opinion essential!) some carrot and onion. (We would tend to use this type of fermented sauce like you would a Tabasco or Encona sauce, for putting on certain types of food, not adding to recipes for that we would use fresh, frozen or dried chillies depending upon what we wanted to achieve)
I have just purchased three Kilner jars with Sterilocks so will try out with these at first, I am going to research the "stikie posts" on fermenting on this. (Going to initially try a wild ferment first)
Will post updates.
Once again thanks for all input.
