Bit of a bargain on the mustard front. 39p - not too shabby - 200g - rotisseur is whole grain mustard whereas Dijon is smooth. An essential ingredient in make-your-own salad dressing - mix top quality extra virgin oil 2 parts to 1 part good vinegar, teaspoon of mustard and a smidge of sugar - mix to smooth consistency & voila!
My other pick of Lidl's French week (starts on Thursday 29/9 but look for items from today onwards) is the 950ml Fish Soup with Norwegian lobster as base. £1.19!
