1. A method of storing cooked food in a food holding bin, comprising: placing cooked food in a food holding bin having a food-contacting surface, at least a portion of the food-contacting surface having an average surface roughness Ra in the range of from about 0.5 μm to about 3 μm;directing radiant energy onto the food while in the holding bin and onto at least a portion of the surface of the food holding bin having the average surface roughness Ra. 2. The method of claim 1 further comprising forming a thin film of cooking oil on the surface having the roughness. 3. The method of claim 1 wherein placing cooked food in the food holding bin comprises placing French fries or chicken nuggets in the food holding bin. 4. The method of claim 1 wherein the food is selected from the group consisting of French fries, chicken nuggets, hash browns, onion rings, fried mushrooms, hamburgers, chicken and mixtures thereof. 5. The method of storing cooked food of claim 1, wherein the average surface roughness Ra is in the range of from about 0.75 μm to about 2 μm. 6. The method of storing cooked food of claim 5, wherein the average surface roughness Ra is in the range of from about 0.75 μm to about 1.75 μm. 7. The method of claim 1 wherein at least a portion of the food-contacting surface comprises a bottom surface of the food holding bin. 8. The method of claim 7, wherein the bottom surface comprises a plurality of openings, the method further comprising separating the placed food from oil by allowing the oil to drip through the openings. 9. The method of claim 7 wherein the bottom surface has an average surface roughness Ra between the perforations of between approximately 0.75 μm and approximately 2 μm. 10. The method of claim 7 further comprising heating the bottom surface to an average temperature in the range of from about 165° F. to about 175° F. by the radiant energy. 11. A method of making a food holding device comprising: providing a sheet of material suitable for a holding bin, at least a portion of the sheet of material having an average surface roughness Ra in the range of from about 0.5 μm to about 3 μm;forming at least a portion of a food holding bin from the sheet of material having a food-contacting surface wherein at least a portion of the food-contacting surface has the average surface roughness Ra. 12. The method of claim 11 wherein the material of the food holding bin is stainless steel. 13. The method of claim 11, wherein all of the food-contacting surface of the holding bin has an average surface roughness Ra in the range of from about 0.5 μm to about 3 μm. 14. The method of claim 11, wherein at least substantially all of the food-contacting surface of the holding bin has an average surface roughness Ra in the range of from about 0.5 μm to about 3 μm. 15. The method of claim 11 further comprising bead blasting the sheet of material to provide the average surface roughness Ra. 16. The method of claim 15, wherein the bead blasting comprises bead blasting with glass beads. 17. The method of claim 15 wherein the bead blasting comprises bead blasting with glass beads having an average grit size of 6 to 80. 18. The method of claim 11, wherein the average surface roughness Ra is in the range of from about 0.75 μm to about 2 μm. 19. The method of claim 18, wherein the average surface roughness Ra is up to a maximum of about 1.2 μm. 20. A method of storing cooked French fries comprising: placing cooked French fries in a food holding bin having a food-contacting surface, at least a portion of the food-contacting surface having an average surface roughness Ra in the range of from about 0.5 μm to about 3 μm;directing radiant energy onto the cooked French fries while in the holding bin and onto at least a portion of the surface of the food holding bin having the average surface roughness Ra. 21. A method of making a food holding bin from a sheet of material comprising: bead blasting at least a portion of a sheet of material to provide a surface roughness Ra in the range of from about 0.5 μm to about 3 μm; andforming at least a portion of a food-contacting surface of the food holding bin from the sheet of material wherein the portion of the food-contacting surface having the surface roughness Ra.
