Columbia Halal Meat in Elkridge specializes in, well, halal meat, but they have a pretty good rice crispy treat for sale at the cash register under the brand Halal Crispy Treats -- 59 cents each, two for a dollar.
Most pre-packaged treats are failures, either too sweet or a soft texture that misses the original. Mrs. HowChow loved Starbucks' version, but someone messed with that recipe about a year ago. In our taste test, we split on the Halal Crispy Treat. I thought it was good -- noticeably less sweet than the official supermarket Rice Crispie Treats and a definite snack options. Mrs. HowChow wants her told Starbucks treat back. She thought the Halal Crispy Treat still had a chemical taste common to prepackaged versions. (They're all still better than the Cheerios and Tang bars that my healthy mother served in decades past.)
