Not Enough Recipe Book [NERB] Mod (1.21.11, 1.20.6) – New Recipes

Not Enough Recipe Book [NERB] Mod is a utility and optimization mod that completely removes the in-game recipe book system for Minecraft on Fabric, Forge, NeoForge, and Quilt loaders. Instead of only hiding the recipe book button, it removes the feature itself to reduce recipe-related player data.

The core problem NERB targets is data bloat from unlocked recipes, especially in large packs where recipe lists can grow heavily. That extra data shows up when reading player NBT and can create friction for scripting workflows, data sync, and world join timing. NERB addresses that by removing recipe book functionality entirely, which is why it has become popular with technical pack makers and server admins, with over 5 million downloads reported on Modrinth.

Key Features of Not Enough Recipe Book [NERB] Mod

• Complete recipe book removal, not just UI hiding — This is the defining behavior: NERB removes recipe book functionality rather than only hiding a button. That matters because hidden UI alone can still leave recipe systems and data in place behind the scenes. If your goal is true cleanup rather than cosmetic change, this approach is more aligned with that objective.
• Reduces recipe-name clutter in player data — The author specifically highlights how fully unlocked recipe books can flood `/data get entity @s` output with recipe names. After installing NERB, those recipe entries disappear from player data. For technical users, that makes player data easier to inspect, script against, and reason about.
• Helps script-driven modpacks (CraftTweaker/KubeJS workflows) — The mod description directly calls out better behavior for CraftTweaker and KubeJS scenarios, especially when using player data in events. Less recipe-heavy data means less overhead when scripts read and process player state. For pack developers, this can make iteration and debugging feel cleaner in daily use.
• Improves server-client data sync behavior — With fewer recipe entries carried in player data, sync between server and client can be faster according to the mod's stated purpose. That improvement is practical in multiplayer environments where every join and resync cost adds up. Even modest reductions in synced data can feel meaningful on busy or heavily modded servers.
• Can speed up world join flow — The mod author states that player world join becomes faster after removing recipe book data payloads. This is especially relevant for players who reconnect often during testing, modpack development, or server administration. It appears to be a lightweight way to trim one known source of player data noise.
• Broad loader and version coverage — NERB supports Fabric, Forge, NeoForge, and Quilt, with files listed across modern versions from 1.18.2 up to 1.21.11. That wide compatibility makes adoption easier across mixed communities and launcher setups. You can keep one optimization concept while choosing the loader ecosystem that fits your pack.

Frequently Asked Questions

What does NERB actually change in Minecraft?

NERB removes the recipe book system itself. It does not just hide the button, so recipe book functionality is taken out rather than visually masked.

Should I install NERB on both client and server?

Yes, you should install it on both sides. The author explicitly recommends client-side and server-side installation for the intended behavior.

Does this mod help with player data size?

Yes, that is a core goal. The mod removes recipe-name entries from player data, which can reduce data clutter seen in commands like `/data get entity @s`.

Is Not Enough Recipe Book [NERB] Mod available for Forge and Fabric?

Yes, it supports both Forge and Fabric. It also supports NeoForge and Quilt across the listed Minecraft versions.

Can this improve CraftTweaker or KubeJS script workflows?

Yes, it can improve those workflows according to the author description. The idea is that less recipe-heavy player data can make `event.player.data` and similar reads more efficient for script processing.

Is NERB still actively updated for newer versions?

Yes, it appears actively maintained based on available metadata. The changelog notes a port to 1.21.11 and the latest listed update date is 2026-02-28.
