This says: "béarnaise dressing (rapeseed oil, vinegar, mustard (water, mustard seeds, vinegar, salt, turmeric), sugar, water, tarragon, egg yolk, natural extracts, herbs, food colouring E160a, salt, onion powder, green tea extract, antioxidant E392, preservative E202, thickener E415, acidifying agent E330)".
So, erm... Why do they need green tea extract in béarnaise sauce? I mean, it's probably better for you than all the Es, but so is chocolate, and I hope that wasn't on the shortlist of ingredients!
Maybe the recipe was optimised by a computer...
