Here's what you need (this is considering you are a level 1 cook):
4 green recipes and the materials listed for each.
1. A level 15 green recipe and 90 of each ingredient
2. A level 25 green recipe and 75 of each ingredient
3. A level 35 green recipe and 85 of each ingredient
4. A level 45 green recipe and 120 of each ingredient
This process will be quicker if you use the Multicraft Addon.
Here's what you do:
1. Make the level 15 recipe until you get to level 20 provisioning (should take a couple less than 90)
2. Put a skill point into Recipe Improvement
3. Make the level 25 recipe until you get to level 30 provisioning (should take a few less than 75)
4. Put a skill point into Recipe Improvement
5. Make the level 35 recipe until you get to level 40 provisioning (should take a few less than 85)
6. Put a skill point into Recipe Improvement
7. Make the level 45 recipe until you get to level 50 provisioning (should take a few less than 120)
Congratulations on becoming a Master Provisioner!!
