Cooking gauntlets are a pair of members-only gloves, available after completing the Family Crest quest. While wearing the gauntlets, the player will have a reduced risk of burning select types of fish. They can be obtained by bringing the magical Family gauntlets (or any of the enchanted gauntlets) to Caleb at Gertrude's house in Varrock. If the gauntlets are enchanted already, it will cost 25,000 coins to change them. Cooking gauntlets give the same 1% experience bonus as sous chef's mitts if the player owns both (as well as the added 1% set bonus if the rest of the Sous chef's outfit is worn).
If you own any of the other Family Crest gloves, you will not be able to get these. Make sure to check your bank for the goldsmith or chaos gauntlets. If the gauntlets are destroyed or lost due to death, these gauntlets may be re-obtained free of charge from Dimintheis in south-east Varrock and will have the same enchantment on them.
The text that appears when you give your gauntlets to Caleb is: "Caleb takes the gauntlets from you, pours some herbs and seasonings on them, bakes them on his range for a short period of time, and then hands them back to you."
