Took cook a meal you need to have Cook's Utensils.
When getting ready to cook a meal as an artisan, the first thing to do is to decide on what you want to cook and ensuring you have the ingredients required for the meal. Below you will find a list of tables with meal names, ingredients, the DC required to cook the meal, and the boon they grant. More recipes will become available to you as you increase your hunter rank. You are able to cook rank 2 meals at 5th level, rank 3 meals at 10th level, rank 4 meals at 15th level.
The ingredients themselves should be easy to obtain. They might find them near the campsite as part of preparing the meal or be able to purchase them in town for for a portion large enough to prepare a meal for a party of four. However, there is always a cost when cooking a meal. Whether you use your supplies to go out and collect local foliage and fauna or purchase it in the market. The cost of preparing a meal depends on its rank. A Rank 1 meal costs 1 sp per serving (4 sp for a party of 4); Rank 2 meals 1 gp (4 gp); Rank 3 meals, 5 gp (20 gp); and Rank 4 meals, 10 gp (40 gp).
As a game mechanic, there are multiple steps in creating a meal: deciding on the recipe/what to cook, gathering ingredients, preparing the ingredients, cooking the meal, plating it properly.
Choose three of the steps from the list above and one of the six main ability scores for each step. You cannot use the same ability score on different steps. Then describe how you use that ability score for the step you chose and make an ability score check. The DM may impose disadvantage on the check if the description is wildly improbable to work or not allow the roll. A creature that is proficient with Cook's Utensils can add their proficiency bonus to one of the three ability score checks.
Once the you have made your three checks, the DM takes the average of the checks and compares them to the DC of the meal you are attempting to make.
On a successful check the meal counts as a days ration for any who eat it and they gain the boon the meal provides. If the artisan succeeds by 4 or more, roll once on the Daily Skill list. If they succeed by 8 or more, roll twice on the Daily Skill list.
On a failed check it becomes a bland meal and counts as 1 days ration. If the artisan fails the check by 5 or more, it does not count as a ration and any creature who eats the meal must succeed on a Constitution saving throw equal to the meal's DC or become poisoned for 1 hour.
At Rank 1 the meal's DC is increased by 1 for each serving over 4. Beginning Rank 2, the meal's DC is increased by 2 for each serving over 4.
Let's look at an Example:
Zuri the half-orc fighter has taken on the role of artisan on a hunt in the Verdant Hills. As the group wakes up in the early morning she begins preparing a meal for all of them. The following is what the player describes:
Zuri looks around and spies some fruit high up in a tree that she thinks she could turn into a sauce. She climbs up the tree (Strength) plucking the fruit as she goes. Back at the campfire with fruit in hand, she thinks about the type of meal she wants to make (Intelligence). Deciding on the meal, Zuri spends the rest of her time over a sweltering hot fire (Constitution) cooking the meal to perfection.
This example doesn't go into excruciating detail, and in some cases allows the player to make some things up. I didn't have Zuri make a perception check to find the fruit, instead the Strength check either allowed her to gather as many as she wanted for the meal or perhaps on a failed save, they aren't ripe, already rotting when she gets to them, or they are on small thin branches preventing her from getting more than few of them. Most importantly, passing or failing on a single check does not matter. What matters is if Zuri succeeded well enough overall to pass the meals check DC.
On a successful check, Zuri was able to create the meal even though she may have experienced a few hiccups along the way and could be narratively described based on the checks that scored below the meals DC. Say she failed on her strength but succeeded on both the intelligence and constitution checks. Narratively it could be described as Zuri struggling to find enough fruit for the meal, but made up for its missing component by adjusting the recipe and taking the meal off the fire a little earlier than normal to deal with this challenge.
On a failed check, Zuri was unable to create the meal as she had planned, this could be due to a lack of fruit she was able to obtain, her recipe was incorrect, or perhaps she removed it from the fire too soon. Depending on how badly she failed the check, it could still be edible, but bland, or it could cause someone some stomach issues for a bit.
