Thank you for suggestions Chris and EvergreenDan. Well, i tried some of the popular cocktails like long island, side car, blue lagoon, screwdriver, woowoo, fuzzy shark, mojito etc. However, I didn't quite find the one I like a lot, probably the one with orange juice, blue curacao and peach schnapps was the best. But the most I enjoy really is just pure cognac, maybe cocktails aren't for me? The reason why I have the schnapps and other random liqueurs was to make some cosmos and strawberry daiquiries for my girlfriend, which she likes a lot, but I find them too sweet. I had a bottle of Campari before, and don't remember what I made, but I think I like bitter taste in general, maybe I should get another bottle and try something with that. So probably if you could advice something rather strong or bitter. Long island was nice too, but so many different variations, maybe someone can suggest a nice one? Many thanks guys
