I found this Tribeca recipe on 2 different sites:
12.5% Double RY4
2.5% Graham Cracker
2% Pyrazine
3% ethyl maltol
10 days to to steep.
That's the basis of the one I use for essentially an ADV. I just lowered the EM to 1% as 3% was just too sweet. After a good mix and leaving the top off overnight it's good the next day, and even better after a week or so.
