My sister shared this tip with me some time back (mysecondcupofcoffee). I like cereal, but do not like crumbs from the bottom of the bag in my bowl, nor do I like wasting cereal to avoid the crumbs. Sis suggested pouring the cereal into a colander, shaking it a bit to get rid of the small crumbs, THEN pouring it into your bowl for milk and eating! It works REALLY well and I never would have thought of doing it!
Anyway... happy cereal-crumb-free breakfasting!
