You may already know this simple and easy trick.
Some baking recipes require you to use a food processor to crush items such as: graham crackers, oreos, biscuits, etc. However, there are many people who do not own a food processor. Here’s an alternative solution.
Fill a Ziploc bag with the item you need to crush – note that this unfortunately is not designed to work with food items such as tomatoes or onions (in case you are making salsa).
Use a rolling pin, your hands, or another kitchen tool to smash the items in the bag until they are ground to the right consistency.
