I have Allepo pepper and have been using it for a long time. I am mad for piment d'
espelette, The aroma is so lovely, and it enhances certain foods so well. It goes great with baked potatoes and turffle butter, and those cream potatoes with nutmeg recently posted. Sally BR posted a recipe for pork tenderloin, I believe that she says really is outstanding. I have it printed but not tried yet.
Aleppo, IMHO does not compare, but it does have its charms.
When I was first introduced to truffle butter by Linda Stradely I fell in love with it....never had I smelled such a wonderful ingredient and I have white and black truffle butter in my freezer at all times, I feel the same about the piment, it is right up there with the truffle butter.
Last week I made a very good chili with sweet banana peppers from my neighbors garden, I also used Aleppo pepper and decided to put in a tsp. of piment. It was the piment that shined. The heat it presents is so delicate and it sneaks up on you. It is just one of those ingredients that I clicked with.
Not sure where I read it but you need to be sure your spice says AOC on the label to make sure you are getting the authentic stuff.
I bought mine through Amazon only after I have tried a very small amount of it first. I went through that small jar in about ten days, then bought in bulk. I keep a small amount in my spice area in a hermetically sealed jar and the rest in a large glass hermetically sealed jar, in a dark, cool pantry area.
