Where are you getting Grande? I have a RD membership, but they don't carry Grande. They have Sorrento, Polly-O, a Saputo product, some brand of shredded cheese, and maybe some others.
If I can't get Grande, I may try the Sorrento and see how it compares to the grocery store version. I've bought a few loaves of the Saputo, but have decided a change is needed. I thought the white cheddar I was mixing in was giving me a subtle taste that I was unsure of. I left out the cheddar on the last pie, and the taste was still there.
