[Sca-cooks] Mint jelly or sauce

[Suey]

In Latin American countries it is very rare to find mint jelly.  I  am 
now out of it but my mint plant is gorgeously big so I think I could 
create jelly. Too when last in England I stayed at a friend's home and 
when she served lamb for dinner she took some mint leaves from her 
garden and mixed them with vinegar and who knows what making a lovely 
mint sauce. I continually ask her for the recipe but she sends me 
nothing. For me eating lamb without mint is a crime. I guess my visits 
to England and North America have always been around mint eating lambs. 
If anyone has a recipe for either I would be most grateful.
