Tips & Techniques > Starting Your Mirepoix Collection Bag

If you make stock often, it’s a great idea to start a mirepoix collection bag. Any plastic container or freezer bag will do just fine. Anytime you’re cooking and have leftover vegetables such as onions, leeks, celery or carrots, just give them a quick chop to the desired mirepoix size and add them to the bag. Store the bag or container in the freezer and when it’s time to make stock, you’re ready to go. Just throw in the frozen mirepoix.
