Could be good in a split?
Also called the Banana Chilli, the Yellow Wax pepper is a milder cousin of the Hungarian Hot Wax. It has a Scoville rating of 0-500 SHU – as compared to a rating of between 500 and 5000 SHU for the Hot Wax. This makes it only slightly hotter than a Bell pepper (a SHU of zero). On this rating scale, it is about hot as a Cubanelle, but milder than an Anaheim pepper. So, it s certainly not a contender in the world heat scales!
This Chilli reaches a length of 5 to 6 inches and has a yellow colour. Its curved shape and colour give it a similar appearance to a banana- thus its name. It is most often eaten in this form, but when allowed to mature turns a red colour. It’s still quite edible and tasty as a mature Chilli, but its characteristic tangy-sweet flavour is best when it is yellow
The Yellow Wax pepper is a cultivar from the Capsicum Annuum species It has its original origins in the Americas, but as with most Chillies quickly made its way around the world (finally landing in Hungary). It came back in its current milder version when it was introduced to the USA by the Corneli Seed company in 1940 (source: The Pepper Lady’s Pocket Pepper Primer by Jean Andrews) as a variant of the Hungarian Hot wax.
Whilst this Chilli is not (that I know of) used to make banana splits, the Scotsman National newspaper reported that there is a restaurant in Scotland that makes a Chilli milkshake. It is apparently made with a sweet Chilli sauce and topped with Chilli powder.
Sounds good to me!
