What proportions (cognac:cointreau:lemon) do you prefer to use for your Sidecars? Most bars here in Stockholm seem to go for 1:1:1 (and then sometimes throw in some simpe syrup to balance all the acid from the lemon), but I find that makes the lemon totally overpowering in relation to the cognac. My personal aim is 2:1:1, which lets the cognac stand out against a nice balance of sweetnes and "citrusness". Some (e.g. Robert Hess) even go for 4:2:1, which I find too sweet. What's your favorite? Does it vary depending on the brand of cognac used?
