The most common collocation of Bailey liqueur is milk, with some ice or without ice. An ordinary beer glass is seven minutes full of milk, plus four bottles of Bailitian wine (the bottle cap of Bailitian). If the cream tastes weak, it can be sweetened with thyme. Bailey liqueur+vodka, the ratio is three cups of Bailey liqueur and one cup of vodka, which is 3: 1. Add ice and stir. If you drink it personally, the proportion is arbitrary. If you want to be strong, add more vodka.
