I'll find the chilli one, but the jelly's easy.
Don't make it just from Rowans, it makes a dreadful tasting jelly and it's just a waste of sugar.
Whatever weight of rowans you gather, use up to three times that weight in apples....windfalls, crabs, whatever's cheap at the end of the day in the supermarket; they all work
Pick the rowans off the stalks, and rinse them and mostly drain. Rinse (wash depending on where you got them) the apples, and cut them up into at least quarters. Put both fruits into a big pot and just barely cover them in water (skimp rather than drown, iimmc) Heat gently, cover and poach them until the fruits are all mushy, you can mash them up with the tattie masher if you like, but it can make it hard to strain to a clear jelly. If you don't mind cloudy, go for it.
Strain the fruits out of the liquid (big sieve lined with kitchen towels if you don't have a jelly bag) let it drip overnight.
Next day measure the liquid you have and pint for pound or litre for kg, add sugar.
Slowly bring up to a rolling boil, making sure the sugar is all dissolved before the liquid boils.
Just make it as ordinary jelly/jam from then on.
It does need a little skimming if you want clear jelly, but it sets well and it's a beautiful rose pink colour and it's tangy and tasty, and bitter like good marmalade
