While I have not purchased this from Amazon I have used it for many years.  It makes a super layer for, my version, of Zuppa Engelesia and mixed with cream can be incorporated for Pate Choux. I don't live in Hollywood any more so it is getting more difficult and thanks to Amazon I find it it available and in larger cans.........  I plan to order soon.

I love these - they taste great.  But I get them in the local Dollar Store. Two stars for the value, five for taste.

I was shocked to see that the bulk version of these Jelly Belly's are just in a cardboard box, no plastic, no nothing. Doesn't seem overly hygienic. Since I didn't open the box for a few months the Jelly Belly's were getting softer and crystallizing [unbeknownst to me] because we live in a wet climate. Hmmm...just be aware that the packaging should be upgraded
