I bought a jar of extra light mayo before I joined WW. I binned it, I thought it was vile. I love mayo, and the light does bear a resemblance to the real thing, the extra light to me bears no resemblance at all!
I'd rather stick to just light, it's lovely on ajacket potato instead of butter!
Somebody else might really like it so you might need to try for yourself lol
But points wise it's 3tbsp (45gms) for 1pp
