In case you don't have a measuring cup, you can measure 1/4 cup using tablespoons. Since there are 4 tablespoons in a 1/4 cup, simply use a tablespoon to scoop or pour your ingredient four times, ensuring each scoop or pour is leveled off for accuracy. If you don't have tablespoons, convert based on alternative measuring units like teaspoons or grams, and utilize a conversion chart or calculator to achieve accurate results.
