What's the Difference Between Roasting and Baking?
While these cooking methods are nearly identical in today's kitchen, there's actually a few things that set them apart.
What's the Difference Between Roasting and Baking? â€” Word of Mouth | The Kitchn
- Structure of the food. This is the primary factor that sets these cooking methods apart. Roasting involves cooking foods that already have a solid structure before the cooking process begins (think, meat and vegetables). Baking involves that lack structure early on, then become solid and lose their "empty space" during the cooking (think, cakes and muffins).
- Temperature. Various sources note that the temperature setting on the oven also distinguishes these two cooking method. Roasting requires a higher temperature (400 degrees F and above) to create a browned, flavorful "crust" on the outside of the food being cooked, while baking occurs at lower oven temperatures (up to 375 degrees F).
- Fat content. While many baked goods contain fat within, an outer coating of fat, such as vegetables or meat brushed with olive oil, is an indicator of roasting.
- Covered pan. Roasting is typically done in an open, uncovered pan, while items that are baked may be covered.
Item 1 - correct as far as I can see.
Item 2 - Pizza is baked in excess of 500' F.
Item 3 - I brush breads, dinner rolls, and other traditionally baked foods with butter and to help brown the crust of many items.
Item 4 - there are a host of quick-breads, custards, breads, cookies, brownies, etc. are all baked uncovered.
This discussion could go on for a very long time as there is no longer hard and fast rules that distinguish baking and roasting. There are some who claim adamantly that roasting involves open fire. Others state that roasting reefers to cooking meat with dry heat. I feel that it can be somewhat regional, or even dictated by the traditions of your family.
Don't sweat the small stuff.
