Very high quality dulce de leche from Argentina. Compared to most brands, it's a bit lighter colored, and the taste is more subdued and milkier. You may or may not appreciate this, as it's not the classic taste that you expect from commercial dulce de leche, but it's by far the closest to the homemade dulce that my grandma used to make. For this, I'd give it 6 stars if I could!
Positive

I have tried various brands of stevia, but I always come back to NuNaturals.  I buy the 12 ounce container because I use it to sweeten everything.  If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you.  I drink a lot of tea, and this is my sweetener.  A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem.  Highly recommended.
Positive

I guess my palate is not as sophisticated as I had thought. I'm a rather adventurous diner but this truffle oil really cashed me out. I tried it on scallops and pretty near had to trash them. I have no idea what amuses people about truffle oil. I gave mine away (ananomously).

Negative
