To cook using a fire, left-click on the item you would like to cook in your inventory so that it becomes outlined in white, then left-click on a fire.
The 'Cook X' option allows a player to cook multiple foods (of the same type) without having to select the item repeatedly. When you use a food item with a Cooking range or an open fire, a screen similar to the one below will appear.
After this screen appears, right-click on the object shown and the option to cook one, five, X or All items will be shown. To cook one item, select the 'Cook 1' option. To cook five items, select the 'Cook 5' option. To cook X amount of food, select the 'Cook X' option and type in the amount of food you would like to cook. To cook all of the same type of food in your inventory, simply select the 'Cook All' option.
[Extracted from Runescape.com:
Cooking is useful, because eating food restores lost Hitpoints. As someone new to the skill, you may find that you may often burn food that you try to cook. The more your level increases, the less food you will burn. As your Cooking skill increases, you will also have access to a wider range of foods that you are able to cook.
You can cook food on an open fire or on a range. ]
You can throw away food that are burnt and net for shrimps and cook them again until your inventory is full of cooked shrimps
Go to the General store
Northwest of Lumbridge Castle and sell those shrimps.
