When its time for a neat tankard of a classic elixir, order a simple bottle. HIC once wrote in a comment- “For the liquor cabinet, I would use equal parts of Brandy, Orange, Bergamot, and Custard. I’d suggest 1.5% each. That is a straight Grand Marnier type flavor. That’s the formula I use for mixed drinks type vapes, and as the base for Grand Marnier’s special flavors. mmmmmmm, one of my favorite liqueurs!” I agree.
Useful as a start for many other recipes- a honey cinnamon GM ice cream; a strawberry cinnamon roll with GM cream cheese; a simple GM soufflé. Mixes well with cherries, cranberries, peaches, raspberries & much more in addition to your margarita mixes.
In recipes, you might highlight the Brandy & Royal Orange at 2%, hold the Bergamot at 1.5%, and play with the Custard some- perhaps 1% Custard & 1% Vienna Cream (FA) + 0.5% Koolada for a simple GM French Vanilla Ice Cream.
All credit for this belongs to HIC, even if he has not released any official recipes of the above. Many comprehend DIY mixing so much more thanks to his contributions to the community. Credit also goes to Alexandre Marnier-Lapostolle who created the sensuous orange flavored liqueur in 1880... and to my bartender, Todd, who has poured me many a Philip's Screwdriver by adding one shot to the usual.
