When making drinks, can you replace...?!
Or will that affect the taste too much?
Answers: ...Grand Marnier with another orange flavored liquor like Triple Sec, Cointreau, or Orange Curacao?
Or will that affect the taste too much?
Only slightly. Cointreau, Grand Marnier and Orange Curacao are just top shelf Triple Secs, only someone with a great appreciation of those brands would be able to tell the difference in a mixed drink.
It depends on what type of drink your making generally use less grand marnier than other orange flavored liqours its pretty strong tasting. Its a brandy more or less so i would'nt substitute triple sec or any liqour for it in a savory or smoky drink in a fruity one it would be ok but your drink is going to either lack in orange flavor or become too sweet as the substitutes you mention have alot more sugar and lack in the robust smoky orange taste of the grand marnier
Listen to Mitchell Winery and disregard what people say about substituting orange juice.
Do not use orange juice - it will change the drink (taste, quality and texture) immensely! Triple Sec will work nicely!
yes you can, you can use orange juice
