This recipe calls for Medjool dates. They are the largest of the date varieties and have a sweet, caramel-like taste and texture that make them perfect for protein date balls. Deglet Noor dates are smaller and have a more firm texture. Medjool dates are considered the créme-de-la-créme of all dates. They are typically found in the produce section of the grocery store. If you've never stuffed a Medjool date with peanut butter for a snack, you definitely need to try it! So good!
