Tried adding a recipe for the block "Quartzite Gravel" from the mod ExtraBlocks but nothing drops from sieving it, even if I have a drop set to 100%. Here's my line of code:

{ "recipes":[ { "id":"extrablocks:tfcgravel", "meta":15, "behavior":"meta_specific", "rewards":[{"id":"gregtech:gt.metaitem.01","meta":516,"amount":1,"baseChance":100},{"id":"gregtech:gt.metaitem.01","meta":8523,"amount":1,"baseChance":10}]}]}
