## Abstract

The invention relates to a food-cooking or -heating appliance, and a method for cooking or heating food using the appliance. The appliance includes a tank (2) for a combustion liquid, a container (3) for food, and a support (1) for holding the tank (2) and the container (3) in position. The tank (2) includes a base (6) and a sidewall (7) inwardly inclined towards the top.

## Claims

### Claim 1

A food-cooking or heating appliance comprising a tank (2) for holding a combustion liquid, a container (3) for receiving food therein and a support (1) for supporting the container (3) in position,
wherein the container (3) comprises an elongated vertical cylindrical part, and
wherein the tank (2) comprises a base (6) and a sidewall (7) inwardly inclined towards a top end of the tank, such that the sidewall (7) forces a flame, formed by combustion of the liquid, towards and rise along the vertical cylindrical part of the container (3).

### Claim 2 (depends on 1)

The appliance according to claim 1, wherein the base (6) is inclined, an elevation thereof being higher proximate the sidewall and lower with distance from the sidewall.

### Claim 3 (depends on 1)

The appliance according to claim 1, wherein the tank (2) is revolution shaped.

### Claim 4 (depends on 1)

The appliance according to claim 1, wherein a diameter of a top end of the sidewall is smaller than a diameter of a bottom end of the sidewall by 2% to 10% of the diameter of the top end of the sidewall.

### Claim 5 (depends on 4)

The appliance according to claim 4, wherein the diameter of the top end of the sidewall is smaller than the diameter of the bottom end of the sidewall by 5% of the diameter of the top end of the sidewall.

### Claim 6 (depends on 3)

The appliance according to claim 3, wherein the tank (2) further comprises an opening zone (10) above the sidewall in the form of an inversed truncated cone, a top end thereof being downward facing.

### Claim 7 (depends on 3)

The appliance according to claim 3, wherein the base (6) defines an inverse cone shaped base zone, a top end thereof being downwardly facing, and the sidewall defines a truncated cone shaped wall zone, a top end thereof being upwardly facing.

### Claim 8 (depends on 7)

The appliance according to claim 7, wherein a height of the base zone is greater than a height of the wall zone.

### Claim 9 (depends on 8)

The appliance according to claim 8, wherein the height of the base zone is double the height of the wall zone.

### Claim 10 (depends on 1)

The appliance according to claim 1, wherein the container (3) includes a hemisphere shaped base.

### Claim 11 (depends on 1)

A method for cooking food by using the appliance of claim 1, the method comprising of the following steps:
placing the tank (2) on a flat surface,
placing the container (3) in the tank (2), the container being held by the support (1) and the container (3) touching the base (6) of the tank (2),
placing food in the container (3),
pouring a predetermined quantity of alcohol in the tank (2), and
lighting, and, in turn, burning, the alcohol.

### Claim 12 (depends on 1)

The appliance according to claim 1, wherein the top end of the tank (2) extends higher than a lower end of the elongated vertical cylindrical part of the container (3).
