I have some ideas about what snacks to drink coffee with. I snickered.
If I drink mousse coffee from Vietnam, I usually mix it with spicy beef jerky or Q-bomb horseshoe cake, because Vietnamese coffee itself is sweet. If I eat something salty properly, it will taste different. Water chestnut cake is vegetarian, and it is good to go with Vietnamese coffee.
If it is white coffee, I will choose the original waffle, which has a small and fresh feeling.
Let's start with pure coffee, which is freshly ground coffee. Because coffee itself is bitter and there is no milk, it needs a slightly sweet snack to match it. Otherwise, if it is too bitter, it may make the stomach unbearable, such as biscuits or puffs.
Sometimes I make fancy coffee, so I buy muffins.
In short, you can try all kinds of combinations, and there will be unexpected surprises.
