Jam Maker Recipe: Canned Tomatoes

🔮 Chinese

2026.07.13: Fixed the bug that the Mod would cause other machine menus to be unable to open in the Rome map. However, the Mod still cannot be used in the Rome map because there are no canned tomatoes, no tomatoes, and no cans in the map.

✨ Function description

background

In the game, the value of many crops can be increased through processing. For example, the value of strawberries can be increased by being made into chocolate, and the value of cranberries can be increased by making wine. Sugar itself has a very low value, but it can increase in value by clinging to other high-value crops. There are not many recipes in the game itself, and most crops actually have no upward path. But the strange thing is that although tomatoes have their own superior product "canned tomatoes", they can't make it themselves. This is too strange. Then this Mod came about, and then I thought that the canned tomatoes I often eat contain apple juice. It just so happens that players will be able to achieve the freedom of green apples before the end of winter in this game, so the ingredients for making canned tomatoes should include apples.

Mod function

This Mod modifies the jam maker recipe:

• Added canned tomato recipe, which can produce a box of canned food through: green apple, sugar, and tomato. The total value of the canned food is slightly higher than the combined value of these crops.

📦 Technical details

• Modification: Implemented through RecipePaper.__initializeVariables pre-patch and BlockJamMachine.__initializeVariables post-patch. The former implements the display of canned tomato recipes in the menu of the jam machine, and the latter implements the production of canned tomatoes.
• Compatibility: No conflicts with other mods found.

Jam Machine Recipe: Tomato Can

🔮 English

2026.07.13: Fixed a bug where this mod caused the other machine menu to fail to open on the Rome map. However, the mod is still not functional on the Rome map, as that map lacks tomato cans, fresh tomatoes, and canned goods in general.

✨ Functional Description

Background

In the game, many crops can increase their value through processing. For example, strawberries can be turned into chocolate, cranberries can be fermented into wine, and sugar (despite its inherently low value) can gain value by pairing with high-value crops. However, the game lacks recipes for most crops to achieve such value-added transformations. It is particularly strange that while tomatoes have an official "tomato canned goods" as their processed form, players cannot craft them manually. This mod addresses this gap. Additionally, inspired by real-life tomato canned goods containing apple juice, this mod incorporates green apples into the recipe, taking advantage of players' ability to freely obtain green apples before winter ends in-game.

Mod Features

This mod adds a new recipe to the jam machine:

• Tomato Canned Goods

Crafted using: green apple, sugar, and tomato. The resulting canned goods have a total value slightly higher than the sum of the individual ingredients' values.

📦 Technical Details

• Implementation
• Recipe Display: Achieved via a pre-patch on RecipePaper.__initializeVariables to show the tomato canned goods recipe in the jam machine menu.
• Recipe Functionality: Implemented through a post-patch on BlockJamMachine.__initializeVariables to enable crafting of the tomato canned goods.
• Compatibility

No conflicts detected with other mods.
