Most of my tepin fruit had only 1, very large seed, it had a searing heat for a few moments.
The pollination thing may explain why my over wintered pods that are ready now are no where near as hot as last year, especially my suryanki cluster - it appears to be sweeter this year and no sizzling heat like last year.
I manually pollinate my plants with a moistened qtip and I touch each flower on the plant but I don't know if my technique is proven as it was just a guess on my part - plus I am no bee though have been told to "buzz off" a lot.
