I feel like this is such a strange one...
Chocolate Frosted Sugar Bombs being on-display, it felt like Watterson didn't include a lot of "name brands" because I thought you couldn't really get away with showing a name-brand without some kind of advertising deal.
So it feels strange to have Crisco mentioned by name and then mom saying "shortening?" as though Watterson (correctly) assumed that vegetable shortening was something most children may not actually be familiar with but they'd be familiar with the name Crisco, as they surely would see that in their parents cupboards.
In 2024, I can't even imagine it, it feels like everyone gets the sort of stuff that would use Crisco straight from a bakery anymore. COVID created a quick resurgence of people baking at home, but I would assume kids these days wouldn't even know what Crisco was at all. The brand name won't help anymore because so few people seem to bake at home.
