When I go for grocery shopping, I would sometimes check out "The World" aisle. It displays the typical Asian foods (instant noodles, sauces, rice, coconut milks), Mexican foods, African foods... I would quickly browse through the Asian section, but what I usually buy are from the British and American section. Yes, I didn't realise Malaysians are influenced in some way by the British : Jacob's crackers, Marmite, Marie biscuit, pudding, peanut butter. And, I got Dr Pepper softdrink for Hubby (influenced by our time in Austin TX).
Marmite is one kind of yeast extra. I grew up eating rice porridge with soya sauce or Marmite. It has a weird taste but I grew to love it. After I moved to France, I didn't eat it for a while, until I found online that it was sold in an Irish shop in downtown Nantes. Now they even have it in some traditional French supermarkets. French in general have not heard of it or couldn't believe that people are eating it. Yes, once a coworker mentioned that his friend from Australia was spreading Marmite on his sandwiches, he couldn't stand the smell so didn't even take a bit.
As of crackers, French generally spread something on crackers and serve them during apéro. Malaysians dip crackers into milo (chocolat drink) as breakfast, I'm not sure French can accept it.
How about pudding? Have not seen pudding being served in any typical French household. Hubby doesn't like pudding nor agar-agar (a popular dessert in Malaysia).
My kids love crackers and Marie biscuit. I haven't let them tried Marmite (ok I found spreading Marmite on a sandwich weird too). Aelig accepted agar agar in Malaysia. Hubby does eat crackers. He learnts to eat British food from a Malaysian. lol
