Eli5 why does something sweet taste less sweet when frozen?

Question

For instance, the otter pops that my kids eat taste less sweet in popsicle form than in liquid form. What dark popsicle magic causes this?

Answer 1

Cold numbs your tastebuds, so you taste things less intensely. That’s also why ice-cream slush (when left in cup for a tad bit too long) is sweeter than ice-cream itself.
