From memory, you can’t send any edible fruit or nuts to Mauritius, or coffee, tea, spices, cereals, malt, starches, wheat gluten, oil seeds, seeds or fruits, vegetable extracts, sugar or sugar confectionery, cocoa or cocoa preparations, any type of cereal, flour, starch or milk product, any pastry cook products, any miscellaneous edible preparations, beverages, spirits, wines, vinegars, animal fodder, tobacco...
I’d give it a miss, if I’m honest, I think it’d be very likely to lead to the parcel being confiscated.
Also remember that you can’t send crackers unless their in the original packaging and unopened; and they may still be stopped on arrival.
