As the title say, a config option to disable the recipes made inside of a fridge would be nice.

Not sure why you would want/need that, like Vanilla recipes, mine are also data driven, pfm:freezing is the id
{ "type": "pfm:freezing", "ingredient": { "item": "minecraft:potion" }, "result": "minecraft:snowball" }
That's the snowball recipe for example, you can use a data pack to add or remove recipes at will so if you wanted to remove the snowball recipe for example you'd make a data pack and under the data/recipes directory add a "snowball_recipe.json" that just had
{ }
inside and the game would load it instead of the mod's and therefore the recipe be disabled, so adding this to the config would not only take up a lot of space but also be redundant. I'm closing this for now.

Of course it uses datapacks.... I just find it vastly easier to have a single config option rather than having to wrestle with loading them into worlds anyone makes (since my packs are public).
