Melitta's rich, flavourful product is a delicious treat comparable to coffees with a much higher price tag. It is a plus that the decaffeinated version does not sacrifice flavour. Highly recommended.

Either I got 15 tubes that came from a bad batch lot or they are not selling the right Harissa. I bought 15 tubes thru Amazon from Parthenon Foods and used 4 of them so far and after putting the whole tube it still isn't spicy at all. Normally a whole tube would get you to sweat a bit!!!!! This seems to be a case of false representation. I buy these tubes in Canada at the grocery store all the time when I am up there and they provide a nice kick and spice (as they should). What's up with dat?

Wow... it's delicious! The kids Love it! We made it for breakfast this morning... the pancakes were eaten in no time at all! The only complaint was that there wasn't more! (actually, it was disappointing that the boxes weren't bigger)
