Jammies-TFC
by VioletHale
Jammies-TFC reworks how jars and jams behave in TerraFirmaCraft, adding lid data and sealing rules for jam preserves.
What it does
Jammies-TFC is an addon for TerraFirmaCraft that changes the Jams Preserves system. Jar lids are returned to the player when a jar is opened, so lids can be reused, and a preserve shows which lid was used to seal it. Sealed preserves stay preserved, and opening one takes a simple right-click. Lid data is driven by data files rather than code, so other content can add lids without changing the mod.
The mod requires TerraFirmaCraft to run, since it is an addon that reworks that mod's food content. It runs on NeoForge 1.21.1 and is distributed with a set of TFC additions by Kuba. Installation covers the server and each player's game. Files are published for NeoForge 1.21.1 only, with 1.1.0 as the latest file from 2026-08-08.
Key features
Returned jar lids
Lids come back to the player when a jar is opened instead of being lost.
Visible seal lid
A jam preserve shows which lid was used to seal the jar.
Sealed preserves last
Jams stay preserved once sealed, so their contents do not spoil while stored.
Quick opening
A preserve is opened with a right-click, with no extra steps needed.
Data-driven lids
New lid types can be added through data files, which keeps lid behavior open to extension.

Use cases
Jam storage on a TFC server
Server owners running TerraFirmaCraft can add the mod so jam preserves behave as the addon intends for every player.
Lid reuse in long runs
Players who make many jars in one world get lids back when they open them, so they do not need to craft new ones each time.
Who it’s for: Players and server owners who run TerraFirmaCraft on NeoForge 1.21.1 and want the jam and jar system reworked as an addon.
How it compares
TFCreate Compat is a NeoForge 1.21.1 compatibility mod under the MIT License, open source, and runs on client and server, so it covers a different part of the TFC ecosystem. TFC Ambiental is also open source under the MIT License, runs on client and server, and reaches NeoForge 1.21.10, which is a wider version range than Jammies-TFC. I Heart TFC is client-side only, not open source, and covers Forge and NeoForge 1.20.1 – 1.21.1, so players can run it alone.
