Breath of the Wild Meat Skewers with a number

[PaigeLynn]

When I make some meat Skewers it puts a number in the first heart and then a few extra hearts

Its shorthands them at intervals of 5 iirc, so it doesnt have to list like 17 hearts for example. ♥¹⁵ ♥♥ for example would indicate that the dish replenishes 17 hearts when consumed.
