Milk allergy: when I'm Grand Supreme Commander...
We have a supermarket chain where I live in Luxembourg called "Grand Frais" (it's a French chain that have 'invaded' Lux).
Hummus is normally a Middle Eastern dip made by blending chickpeas with tahini, garlic, and citrus - and I love it! However, the 'Grand Frais' version tastes of nothing and contains 'fromage frais' - unpressed cheese curd!
'Fromage Frais' has no place in Hummus, AT ALL and of course people who have an allergy to dairy may well think they are buying a dairy free product as the standard recipe for Hummus is completely dairy free, but that is not the case!
