The original recipe called for two jalapeños. My jalapeños were pretty large so I only used 1 and a half chopped jalapeños in the recipe. The level of heat is just right for me but you may want to adjust the quantity of peppers you use to suit your taste.
After a day with this quite good recipe, I decided to switch it up a bit and added the segments from one Satsuma tangerine and one peeled and chopped Granny Smith apple. Great!
