Cheese doesn't reach the edges, leaving bald patches
CosmeticAn under-coverage habit distinct from a bare rim border left on purpose — check the edge specifically when topping.
Ask yourself
- Was cheese added from the centre outward, or scattered across the whole surface including near the edge?
- Is this happening consistently at the same point in your topping routine?
Likely causes
- #1
Cheese added centrally and not spread all the way to the intended edge
Generally acceptedThe same central-pile habit that causes general unevenness disproportionately affects cheese, since it's usually added in fewer, larger handfuls than other toppings.
- #2
Deliberately leaving a bare rim border but also leaving cheese short of where it should end
Supported, with regional variationA bare rim border for a raised-rim style is intentional and correct; cheese falling short of that border rather than reaching right up to it is not the same thing and is usually just under-coverage.
Rescue it now
Add a final light scatter of cheese specifically toward the edges before baking
Prevent it next time
Cover the surface up to the intended border deliberately, checking the edge specifically rather than relying on cheese spreading itself during the bake
