## Abstract

A baking pan that includes a base having an interior surface including an interior center top surface and an interior peripheral bottom surface and a sidewall terminating at a top edge in a formed lip and transitioning at a bottom edge into the base. The sidewall has an interior sidewall span at the top edge. At least a portion of the base interior surface slopes upwardly from the interior peripheral bottom surface to the interior center top surface. The base interior surface does not slope downwardly from the interior peripheral bottom surface to interior center top surface. A vertical distance between the interior center top surface and the interior peripheral bottom surface does not exceed 10 percent of the interior sidewall span.

## Claims

### Claim 1

A baking pan comprising:
a base having an interior surface including an interior center top surface and an interior peripheral bottom surface; and
a sidewall terminating at a top edge in a formed lip and transitioning at a bottom edge into the base, the sidewall having an interior sidewall span at the top edge,
wherein at least a portion of the base interior surface slopes upwardly from the interior peripheral bottom surface to the interior center top surface,
the base interior surface not sloping downwardly from the interior peripheral bottom surface to interior center top surface,
a vertical distance between the interior center top surface and the interior peripheral bottom surface not exceeding 10 percent of the interior sidewall span.

### Claim 2 (depends on 1)

The baking pan of claim 1, wherein the sidewall is substantially vertical.

### Claim 3 (depends on 2)

The baking pan of claim 2, wherein the vertical distance between the interior center top surface and the interior peripheral bottom surface is between 5 and 15 millimeters.

### Claim 4 (depends on 3)

The baking pan of claim 3, wherein the interior center top surface is substantially flat.

### Claim 5 (depends on 4)

The baking pan of claim 4, wherein a length of the interior center top surface is between 50 and 150 millimeters.

### Claim 6 (depends on 1)

The baking pan of claim 1, wherein the sidewall slopes outwardly from the sidewall bottom edge to the sidewall top edge.

### Claim 7 (depends on 6)

The baking pan of claim 6, wherein the vertical distance between the interior center top surface and the interior peripheral bottom surface is between 5 and 15 millimeters.

### Claim 8 (depends on 7)

The baking pan of claim 7, wherein the interior center top surface is substantially flat.

### Claim 9 (depends on 8)

The baking pan of claim 8, wherein a length of the interior center top surface is between 50 and 150 millimeters.

### Claim 10 (depends on 6)

The baking pan of claim 6, wherein the sidewall forms an angle of 5 to 30 degrees from vertical.

### Claim 11 (depends on 10)

The baking pan of claim 10, wherein the interior center top surface is substantially flat.

### Claim 12 (depends on 11)

The baking pan of claim 11, wherein a length of the interior center top surface is between 50 and 150 millimeters.

### Claim 13

An insert for a baking pan having a bottom wall and a sidewall terminating at a top edge in a formed lip and transitioning at a bottom edge into the bottom wall, the sidewall having an interior sidewall span at the top edge,
the insert comprising a base having an interior surface including an interior center top surface and an interior peripheral bottom surface,
a vertical distance between the base interior center top surface and the base interior peripheral bottom surface not exceeding 10 percent of the interior sidewall span.

### Claim 14 (depends on 13)

The insert of claim 13, wherein the vertical distance between the interior center top surface and the interior peripheral bottom surface is between 5 and 15 millimeters.

### Claim 15 (depends on 14)

The insert of claim 14, wherein the interior center top surface is substantially flat.

### Claim 16 (depends on 15)

The insert of claim 15, wherein a length of the interior center top surface is between 50 and 150 millimeters.

### Claim 17

A baking pan comprising:
a base having an interior surface including an interior center top surface and an interior peripheral bottom surface; and
a sidewall terminating at a top edge in a formed lip and transitioning at a bottom edge into the base, the sidewall having an interior sidewall span at the top edge,
the sidewall slopes outwardly from the sidewall bottom edge to the sidewall top edge,
a vertical distance between the interior center top surface and the interior peripheral bottom surface not exceeding 10 percent of the interior sidewall span.

### Claim 18 (depends on 17)

The baking pan of claim 17, wherein the vertical distance between the interior center top surface and the interior peripheral bottom surface is between 5 and 15 millimeters.
