It was cheaper pre MUP... its not a direct replacement as you need to use a lot more. I used it more as a replacement for both bitters and cointreau / triple sec.
Own brand brandy or cognac
Lots of Orange Peel (2-3 Oranges)
Fill into a 250ml - 330ml glass bottle
Keep in the fridge
After 48 hours give it a try
