Bla Band sauces are quick and easy to make, and taste good. A great helping hand for a weeknight dinner. How to; 1. Whisk the bag contents in 150ml of cold water. 2. Boil the sauce while stirring and simmer for 30 seconds. 3. Remove the saucepan and add the 50g butter(for a leaner sauce just use 25g fat). Whisk until the butter has melted. This one is particularly nice with meatballs.
