At least we got some smarty bois here.
m&ms. smarties have a coating that's too thick. Unlike with m&ms, thin coating, more chocolate, smarties have a thicker coating, in turn meaning less chocolate. NOT ONLY THAT, but smarties are also thinner than m&ms, meaning even less chocolate overall.
My last point being that with smarties, you can only taste the shell, but with m&ms, it's mostly the chocolate. i prefer the taste of chocolate over the taste of candy shell, but that's just my opinion. i just don't like the taste of smarties' shell.
Actually, Smarties are larger then M&Ms, and they have more chocolate in them. https://images.weserv.nl/?url=idsgn.org/images/parallels-fizzers-rockets-smarties/m&m_smartie.jpg Besides that, imo you need a good shell as it provides texture and a contrast to the chocolate. Nobody wants a mouth full of just chocolate, have you ever tried to eat a whole chocolate bar at once? No, you take small bites and savour each one until it's melted through and there is nothing left. Purely subjective though.
Also uh I'm allergic to peanuts so there's that.
what kind of m&ms are you eating that would fill your entire mouth?
