I ordered the spotted dick. After eating I felt a little strange. I went to the bathroom and to my horror realized that I had this horrible disease. Luckily 1 gallon 128 Floz Tuscan Whole Milk cleared this up for me.

It always amazes me that there are not dozens of reviews here extolling the fine qualities of this tea.  I have drunk it pretty much every day for the last five years and I never get tired of it.  It's an excellent morning tea, is smooth without being insipid, and is almost impossible to ruin by oversteeping. Just use decent water.  I like a little stevia in it, as I'm a wimp. It brings out the natural sweetness of its malty, slightly floral style.  I just bought another two pounds.

Just a few observations here: 1) We have a small chihuahua. These are way too big for her. We basically have to crush them to crumbs for her to eat them. Otherwise she carries them and hides them like bones, and, trust me, it's no fun to find to find a slobbery lamb/barley biscuit under your pillow when you go to bed! 2) What the heck is barley doing in a dog treat? It doesn't seem to me that dogs were designed to graze in barley fields, so why are we feeding them barley? 3) My dog seemed to really enjoy the flavor, so these at least have that going for them.
