11 The Jam Maker is a crafting station in Starsand Island that converts fruit and sugar into fruit jams. These jams serve as intermediate cooking ingredients for mid-tier and high-tier recipes, particularly desserts and pastries. Jams can also be sold directly for profit, making the Jam Maker one of the most important processing stations for both cooking and money-making.

1212 Load the Jam Maker with fruit and sugar. Each batch requires 2 fruits of the same type plus 3 Sugar. The station processes the inputs over approximately half an in-game day and produces the corresponding fruit jam. Different fruits produce different jam varieties.

1515 Jams are not edible on their own. They are intermediate cooking ingredients used in recipes that call for jam or fruit preserves. Some jams (like Tomato Ketchup) function as condiments in savory recipes rather than sweet dishes.

1919 The Jam Maker can produce 16 different products. The jam variety depends on which fruit you load into the station.

2424 The Jam Maker is one of four timed processing stations that produce intermediate cooking ingredients. All four unlock through Farming profession progression at the Happiness Seed Shop.

2727 Note that the Separator processes ingredients instantly, while the Jam Maker, Brewing Barrel, and Pickling Jar all take time. Building multiples of these timed stations is the only way to increase throughput.

2929 Money Making with Jam
3030  
3131 Finished jams sell for significantly more than raw fruit. Individual jams sell for around 500 coins or more each, making jam production one of the most profitable processing activities in the game. The key to maximizing profit is scale: building 10 or more Jam Makers and running them simultaneously.
3232  
3333 To set up a profitable jam operation:
3434  
3535 Plant large orchards of fruit trees on irrigated fields. Fruit trees regrow their produce every few days without replanting.Keep a steady supply of Sugarcane or Sugar Beets growing for Sugar production at the Separator.Build 10 or more Jam Makers and place them in a cluster for easy loading and collection.Load each station with 2 fruit and 3 sugar. After half a day, collect the finished jams.Sell in bulk at the Merchant Ship for premium prices. The Merchant Ship pays roughly double what regular vendors offer for select goods.
3636  
3737 GMax fruit variants (grown from GMax seeds) produce jam with a higher value multiplier, further increasing profit per batch. If you have access to GMax crops, prioritize using those fruits in your Jam Makers.
3838  
3939 Automation
4040  
4141 While the Jam Maker cannot be fully automated through conveyor belts or hoppers in the current version, you can optimize the workflow by clustering Jam Makers near your fruit storage and Separator. The basic loop is: harvest fruit, process Sugarcane into Sugar at the Separator, load Jam Makers, wait half a day, collect. With enough stations running in parallel, daily jam income can reach 100,000 coins or more. See the automation article for general tips on streamlining production chains.

4343 Scaling for Maximum Profit
4444  
4545 The real money from jam comes from running many stations simultaneously. A single Jam Maker produces modest income, but the profit scales linearly with the number of stations you build.

5050 Plant GMX apple or watermelon seeds on irrigated fields near your Jam Makers.Process beets into sugar at the Separator to maintain a steady supply.Harvest fruit trees using a charge attack to conserve stamina. Trees regenerate every few days without replanting.Load each station with 2 fruit and 3 sugar. Processing takes roughly half a day per cycle.Collect finished jams and sell at the Merchant Ship for 200% value (double the normal shop price).

5252 Selling exclusively through the Merchant Ship effectively doubles your revenue. Combined with 10+ stations, this setup can generate over 100,000 coins per in-game week.

5454 Tips
5555  
5656 Build the Jam Maker alongside the Brewing Barrel and Pickling Jar. All three stations produce intermediate cooking ingredients that advanced recipes require.Keep a steady supply of Sugarcane growing. Sugar is required for every jam batch, and Sugarcane is an all-season crop that never goes out of rotation.Process excess fruit into jam rather than selling raw fruit. The price increase from raw fruit to finished jam is substantial, even before factoring in Merchant Ship bonuses.Watermelon and Star Mango are popular choices for mass jam production because their trees produce large quantities and the resulting jams have strong base sell values.Place a storage chest next to your Jam Maker cluster to stockpile fruit and sugar. This saves trips back and forth to your main storage.Jams stack in your inventory, so storage is not an issue even with high-volume production. Sell them in batches whenever the Merchant Ship is in port for the best return.
