Green chillis

Green chillies are unripe versions of red ones and they will continue to ripen off the plant, just like tomatoes.

The only way I can think of to dry them green would be to do it in a very low oven so they dry more quickly, but don't know if the colour would change.  It does a bit when you dry them in a dehydrator  

I did make some preserved red chillies last year by finely chopping them, putting them in small sterlized jars and pouring over a hot vinegar/sugar mix which was 8oz sugar boiled with 1 pint white malt vinegar.  The vinegar comes in 568ml bottles, which is a pint.  I keep the jars in the fridge once opened. On my last one now and they are still full of the fresh chilli taste    I did this with home grown scotch bonnet chillies, hence the sugar to moderate the heat a little.  You could just use hot vinegar  

I grew Menorca last year and they stayed green. I froze them and am still using them 

I think it does - same as sweet peppers.  Green chilli has a fresher more vegetable taste, whereas the fully ripe ones develop the full flavour of the chilli, which can be quite complex depending on the variety  

This is a good link someone put on here - this lot sell all sorts of chillies and give some good info on heat levels and uses    They have a special Curry Chilli if you scroll down the page.

Chillies are so easy to grow and there are so many to try.  This year I'm growing Ancho (chocolate chilli) and Lemon Drop (hot), which are new to me.  Also Pretty in Purple (hot) which dry beautifully and are perfect for crumbling into dishes.  These are very fragrant and almost fruity smelling when you open the jar  

I love Lemon Drop! A good, warm to hot chilli that is so prolific it's unbelievable    Fruity and lemony so live up to their name. Good with rice dishes I think.  I froze loads and they keep their colour beautifully. I dried some too but they go a manky colour then
 

Thank you for the info - will save the drying for the Pretty in Purple
