The basic recipe for fish-house punch involves cognac, dark rum, peach brandy, sugar, and lemon. I have peach schnapps, which I rather like. However, this blend is one of the few that I find palatable with this much alcohol in it; much like Long Island Iced Tea, it tastes a lot less boozy than it is. If I substitute peach schnapps for peach brandy, will it throw off the balance of the drink? Or possibly add any unwanted flavors?
ETA: When I went to the store, I discovered Paramount brand "Peach-flavored Brandy". The back of the bottle suggests using it in a Fuzzy Naval, which is one of the drinks I usually make with Peach Schnapps. I kind of wonder if it's just got artificial flavors rather than being distilled from peaches? It's a product of Cleveland, which is near where I live, so I don't know how widely available that brand is.
