Aleppo chili flakes are smoky and tangy and less harsh than typical red pepper flakes.
Spice blend- If you like harissa flavors, and want to be able to make more of harissa recipes, consider making a full batch of my
Easy Homemade Harissa Spice Blend in place of the listed spices here.
The caraway and sumac are listed as optional since you may be less likely to have them on hand. Caraway lends a nuttiness and is present in most harissa pastes, and sumac lends a tang.
The Colgin’s liquid smoke is totally optional, but I’ve come to like the subtle authentic smoked flavor it brings recipes and it makes the sauce really come alive.
Carrot tops-if your carrots come with the tops attached, they taste vaguely like carrots and fairly mild, but if you don't have access to carrot tops, cilantro or parsley work, whichever you like the taste of more.
Coating Mushrooms-as you use your hands to coat the mushrooms with the sauce, the larger clumps will start to break apart some. Don't press too hard, but it is ok that some break apart (see photo of mushrooms on grill). You don't want them to break apart into too many small pieces or it will be hard to grill them without them falling in between grill screen. You can break them up more after grilling.
