So we creamed the butter and the brown sugar, added in the eggs, then went to blend in the milk, when things took a turn for the weird!
The butter/sugar/eggs has sort of set, with a curdled look to it. The milk has taken on the colour of the brown sugar, but other than that they all simply refuse to be mixed - think oil/water only thick and chunky (sorry it sounds gross, looks worse!)
I guess I added the milk too fast and should have added/mixed/added/mixed... ??? Can I rescue it, d'you reckon, or is this just one for Experience?
