Although I didn’t this past summer, I’ve grown pepper plants here in Alberta in previous years. They can get plenty hot!
Xanthan gum is another option that’ll work. My store doesn’t have guar, but they sell xanthan. I don’t use it for salsa, but occasionally I will use it to thicken a vinegary hot sauce. A little goes a long way, and the advantage of xanthan vs traditional thickeners like corn starch or similar is that it doesn’t require heating.
Yeah, the typical hot pepper in Hungarian food is usually something along the lines of an Anaheim pepper. They look quite similar. They can actually get somewhat toasty if you eat them in a big quantity, but they don’t have that sharp concentrated heat like a Thai or even cayenne.
Or come to Montreal and have both hot salsa and hot Canadians
Seriously, we’ve got a range of salsas (including hot) at any decently-sized supermarket, various Mexican hot sauces at larger ones, and a wide international variety of hot sauces at ethnic and gourmet markets.
That is no lie(about the hot Canadians). We played Jazz Fest in 2010 and there was a heat wave, the ladies just wore sheer, tiny dresses with sandals and nothing else. It was a sight to behold, wow.
As to Salsa. My personal favorite is Mrs. Renfro’s Habanero Salsa. They have several varieties and IMO all are very good. Amazon carries them, so you may be able to get them in Canada.
Happy Salsa hunting
