Abstract

A method for grilling food on grill includes adding chipped wood charcoal having a size of at least one-fourth an inch in dimension through a food-supporting grill grate onto a grid underlying the food-supporting grill grate. The food-supporting grill grate comprising spaced bars for supporting food and providing a cooking area, and the chipped wood charcoal can be added to the grid directly beneath any portion of the cooking area by passing the chipped wood charcoal between any adjacent ones of the spaced bars. The chipped wood charcoal is ignited and food is placed on the food-supporting grill grate over the chipped wood charcoal. The food can then be cooked on the food-supporting grill grate. Without lifting any portion of the food-supporting grill grate and during the cooking of the food, more chipped wood charcoal is added through the the spaced bars of the food-supporting grill grate. The chipped wood charcoal can be added to the grid directly beneath any region of the cooking area by passing the chipped wood charcoal between any of the adjacent ones of the spaced bars.

Claims (28)

1. A method for grilling food on grill, the method comprising:

adding chipped wood charcoal having a size of at least one-fourth an inch in dimension through a food-supporting grill grate onto a grid underlying the food-supporting grill grate, the food-supporting grill grate comprising spaced bars for supporting food and providing a cooking area, wherein the chipped wood charcoal can be added to the grid directly beneath any portion of the cooking area by passing the chipped wood charcoal between any adjacent ones of the spaced bars;

igniting the chipped wood charcoal;

placing food on the food-supporting grill grate over the chipped wood charcoal;

cooking the food on the food-supporting grill grate; and

without lifting any portion of the food-supporting grill grate and during the cooking of the food, adding more chipped wood charcoal through the adjacent ones of the spaced bars of the food-supporting grill grate, wherein the more chipped wood charcoal can be added to the grid directly beneath any region of the cooking area by passing the chipped wood charcoal between any of the adjacent ones of the spaced bars.

2. The method of claim 1 , wherein the adding of the more chipped wood charcoal through the food-supporting grill grate comprises adding more chipped wood charcoal through the food-supporting grill grate without substantially interrupting the cooking.

3. The method of claim 1 , wherein the spaced bars of food-supporting grill grate comprises consistently spaced bars.

4. The method of claim 1 , wherein the grid comprises solid non-perforated side edges and a bottom perforated portion, the solid non-perforated side edges extending one-half inch or less from the bottom perforated portion on each side of the grid.

5. The method of claim 1 , further comprising installing the grid to the grill by lifting the food-supporting grill grate and disposing the grid on top of an existing support within the grill, wherein the existing support comprises a solid fuel support grate configured to support charcoal briquettes.

6. The method of claim 5 , wherein the grill is a gas grill, and wherein the existing support comprises heat spreaders of the gas grill and the igniting comprises starting the gas grill.

7. The method of claim 6 , wherein the heat spreaders are one of radiant bars, lava rocks, or drip shields associated with a gas or propane burner.

8. The method of claim 1 , wherein the chipped wood charcoal is smaller than a particular size less than three-eighths inches in their longest dimension.

9. The method of claim 1 , wherein the chipped wood charcoal is sized by separating other pieces of wood charcoal and wood charcoal dust from the chipped wood charcoal by passing the chipped wood charcoal, the other pieces of wood charcoal and the wood charcoal dust over a screen allowing the other wood charcoal and the wood charcoal dust to be removed and keeping the chipped wood charcoal that is sized between one quarter to three-eighths of an inch.

10. The method of claim 1 , wherein the grill is a natural gas grill or a propane gas grill.

11. The method of claim 10 , wherein igniting the chipped wood charcoal comprises igniting the chipped wood charcoal using natural gas for the natural gas grill or propane gas for the propane gas grill.

12. The method of claim 11 , further comprising turning off the natural gas or the propane gas upon igniting the chipped wood charcoal.

13. The method of claim 1 , wherein adding the chipped wood charcoal through the food-supporting grill grate onto the grid comprises adding chipped wood charcoal through the food-supporting grill grate directly onto the grid, and wherein the grid comprises three-eighths inch round or five-sixteenths inch square perforations that make up 39% to 44% of a surface area of perforated portions of the grid.

14. A method for adding chipped wood charcoal to a grill, the method comprising:

adding the chipped wood charcoal having a size of at least one-fourth an inch in dimension through a food-supporting grill grate onto a grid underlying the food-supporting grill grate, the food-supporting grill grate comprising spaced bars for supporting food and providing a cooking area, wherein the chipped wood charcoal can be added to the grid directly beneath any portion of the cooking area by passing the chipped wood charcoal between any adjacent ones of the spaced bars;

igniting the chipped wood charcoal; and

without lifting or moving any portion of the food-supporting grill grate and during burning of the chipped wood charcoal, adding more chipped wood charcoal through the adjacent ones of the spaced bars of the food-supporting grill grate wherein the chipped wood charcoal can be added to the grid directly beneath the any region of the cooking area by passing the chipped wood charcoal between any adjacent ones of the spaced bars.

15. The method of claim 14 , wherein the spaced bars of the food-supporting grill grate comprises consistently spaced bars.

16. The method of claim 14 , wherein the grid is on top of an existing support within the grill.

17. The method of claim 16 , wherein the grill is a gas grill, and wherein the existing support comprises heat spreaders of the gas grill and the igniting comprises starting the gas grill.

18. The method of claim 17 , wherein the heat spreaders are one of radiant bars, lava rocks, or drip shields associated with a gas or propane burner.

19. The method of claim 14 , wherein the chipped wood charcoal is smaller than a particular size less than three-eighths inches in their longest dimension.

20. The method of claim 14 , wherein adding the chipped wood charcoal through the food-supporting grill grate onto the grid comprises adding chipped wood charcoal through the food-supporting grill grate directly onto the grid, and wherein the grid comprises three-eighths inch round or five-sixteenths inch square perforations that make up 39% to 44% of a surface area of perforated portions of the grid.
