I replaced the tuna with salmon in this fresh spring salad.
The chillipepper natively originates from South America. The tiny long versions are less potent than the round South American versions. Contrary to popular belief, seeds are not the hottest part of the chilli, it is in fact the membrane to which they are attached (the white bit or pith).
The Scoville Heat Unit is the heat measurement of a chilli. It is named after Wilbur Scoville, an American Pharmacist, who in 1912 devised the “Scoville Organoleptic Test” to measure the spicy heat, or piquancy, of chilli peppers.
Tabasco is about 3000 Scoville Units, The Carolina Reaper, the current World Record holder is about 2.000.000 Scoville units... go figure!
If you want to reduce the heat after eating a bit too much: the heat comes from capsaicin, which binds to your tongue receptors. It dissolves in milk, NOT WATER. So drinking a little milk might help. Remember: your receptors get used to eating hot food so the more you eat it, the less pain you will feel. In Thailand spicy dishes are often also very sweet, since sugar lowers the intensity of the effect.
