that sounds lovey what quantities of flour, Eggs & water did you use.
I usually use Tesco batter mix cause I am useless at getting the right consistency for batters. The whole packet is 9.5syns but does make a big enough toad in the hole for two. and the sausages I use are only 1syn each.
I only have two sausages so with the batter it works out at about 6.25syns which isnt to bad as long as I dont have it to ofter.
