Problems with creating a mod

[NobodyCares69]

I don't really know if that counts as modding but I was trying to add a new recipe to the game, because the underground worms weren't spawning at all. I added this line to the recipes.lua:

--MY RECIPE BEGIN
Recipe("wormlight", {Ingredient("berries", 1), Ingredient("lightbulb", 3)}, RECIPETABS.REFINE, TECH.NONE)
--MY RECIPE END

But it doesn't show up in the game. Did I do anything wrong?
