Gluten-Free Bakery in Philly Area
i was all ready to help when i saw the title, because i was going to suggest Mr. Ritts...and then i read the body of your post. bummer!
i checked the website, and there's a natural food store in Springfield that's listed as a reseller. perhaps you could contact them to find out what kind of selection they have...
Martindale's Natural Foods
1172 Baltimore Pike
Springfield, PA 19064
as a last resort, you could always have the NJ Mr. Ritts ship you an order.
No need to go to Springfield. Whole foods has lots of stuff. Also Wegmans in Cherry Hill. Are you looking for something specific? Sazon gets gluten free cheescakes that are made locally. they might sell you a whole one if you need it. They are wonderful. They also have GF truffles and creme caramel.
On days when Main Line Baking Co. is not open, I found that i can purchase their products at Martindale's. They carry their cupcakes, muffins and other items. They come frozen, but taste great when thawed. www.MainLineBakery.com
Other great places to shop for gluten-free is Giant and Wegmans (soon to be opening in King of Prussia - Yeah!)
