Ducc-The-Ultimate's announcement temp (cool)

Yes, bread almost universally tastes better than a key.

Here's why:

Bread is food: It's made from edible ingredients (flour, water, yeast, salt) specifically designed for consumption and flavor. It has a range of textures (soft, chewy, crusty) and flavors (sweet, savory, tangy).
A key is metal: Keys are typically made of brass, nickel silver, steel, or other metal alloys. These materials are not meant to be eaten. They taste metallic, often bitter, and can even be harmful if ingested.
So, while "taste" is subjective, in this comparison, bread is the clear winner for edible enjoyment!
