Things were cooking at Blashford yesterday afternoon as I boiled up some "Moth gloop", this is a sugar mixture that attracts moths to feed. My recipe is about half a tin of black treacle, half a can of beer and a box of mollasses sugar, a drop of rum is added before use.
I heat the sugar and treacle and then thin with the beer, ending up with a kind of runny toffee that when brushed onto tree trunks, just slowly rolls down.
Care needs to had when adding the beer,or you can get a boil-over. You also need to check the flow from time to time by putting a little on a cold plate, if too runny add more sugar, if too stiff more beer.
