For this one, you can use either a cupcake casing or a normal coffee filter, as they both work equally well. This will keep your counters from getting too messy due to the grinding process and save you time. Just place your filter or casing over your coffee grinder while you're grinding your beans, then use it as a strainer after you finish, and that's all there is to it.
This simple hack will ensure that your counters stay as clean as when you started, and you won't have to worry about a mess while brewing your favorite cup of coffee.
