Books and Resources to Start Strong
Starting a jam and preserves business requires knowledge of food safety, recipe development, and small business operations. These books will give you the foundation you need to make decisions about equipment, processes, and scaling your operation.
The Ball Canning Guide by Jarden Home Brands
This is the reference manual for water bath and pressure canning. You’ll use it constantly to verify processing times, understand altitude adjustments, and troubleshoot issues like soft set or spoilage. It’s the gold standard in home preservation and trusted by both hobbyists and commercial producers.

Small-Scale Preserving by Annie Proulx and Lew Nichols
This book bridges home preservation and small commercial production. It covers equipment needs, batch scaling, yield calculations, and regulatory basics—all the practical details you’ll need when moving from making jam for yourself to making it for customers.

Starting Your Small Agribusiness by Heather Toon
Jam and preserves count as a value-added agricultural product. This book walks you through permits, licensing, food safety plans, liability insurance, and how to work with your state’s department of agriculture. It’s essential for understanding the regulatory landscape before you buy your first pot.

Essentials of Food Science by Susan Brewer
Understanding pH, pectin, sugar concentration, and water activity isn’t optional—it’s how you prevent spoilage and maintain food safety. This textbook is thorough but accessible, and it helps you make informed decisions about your recipes and processing methods rather than just following formulas blindly.

Equipment You Need
Jam and preserves production requires specialized equipment for cooking, canning, and packaging. Some items are essential from day one; others you can add as production grows. Your choice between home kitchen production and a licensed commercial kitchen will affect what you need to buy.
Core Cooking Equipment
- Large stainless steel pot (10-20 quart capacity): Jam requires heavy-bottomed pots to prevent scorching. A 16-20 quart pot gives you room to reach a rolling boil without spillover.
- Copper or stainless steel jam pan: Copper conducts heat evenly and cools quickly, reducing cooking time. Stainless steel works but takes longer. A 10-12 quart capacity is standard.
- Candy or deep-fry thermometer: Essential for monitoring temperature. Jam reaches gel point around 220°F, so accuracy matters.
- Long-handled wooden spoon: Stainless steel or silicone stirring spoon. You need length to keep your hands away from hot jam.
- Jar lifter: Safely removes hot jars from boiling water. Not optional—burns are common without one.
- Wide-mouth funnel: Speeds up filling jars and reduces mess. Stainless steel or plastic, ideally sized for both quart and pint jars.

Canning and Processing Equipment
- Boiling water bath canner: Large pot with rack for processing jars. Most jams and preserves use water bath canning (no pressure canner needed).
- Canning rack: Keeps jars off the bottom of the pot. Stainless steel racks last longer than wire mesh.
- Mason jars (pint and half-pint): Buy quality jars—they’re reusable for years. Half-pints are popular for gifts and retail; pints for home use.
- Lids and bands: Lids are single-use (one application per lid). Bands are reusable but will corrode over time.
- Bubble remover and headspace tool: Two-in-one tool ensures proper fill and removes air pockets before sealing.

Ingredient Preparation
- Food mill or chinois: Strains fruit pulp for seedless jams and jellies. A food mill is cheaper; a chinois is faster.
- Colander: Drains fruit after washing. Stainless steel won’t stain or corrode.
- Sharp chef’s knife and cutting board: Fruit prep is tedious without good tools. Wood or plastic cutting boards prevent cross-contamination.
- Kitchen scale: Precision matters in jam recipes. Digital scales accurate to 0.1 ounces are inexpensive and reliable.
- Measuring cups and spoons: Volume measurements are less accurate than weight, but still necessary for some ingredients.
Cooling and Storage
- Cooling racks: Jars cool and seal better on racks than on countertops. Wire cooling racks are fine.
- Clean towels or kraft paper: Jars are placed on these while cooling to protect surfaces and catch drips.
- Dry storage shelves: Jams need a cool, dark place (50-70°F). Metal shelving is durable and doesn’t absorb moisture.
Optional But Useful
- Pectin powder or liquid: Not all fruits need added pectin, but it gives you more control over set. Different types work differently.
- pH meter: For safety verification. Most jams are below pH 4.0, which prevents botulism. A basic digital meter costs $20-40.
- Induction cooktop: If you’re using a shared commercial kitchen, a portable burner lets you work independently. Look for 1800-3000 watts.

What to Buy First vs Later
Your initial purchases should cover the essentials for producing safe, quality jam. Buy later as volume increases.
- Month 1 (Essential): Large jam pot, boiling water bath canner with rack, thermometer, jar lifter, mason jars and lids, wooden spoon, kitchen scale, Ball Canning Guide.
- Month 2-3 (High Priority): Food mill or chinois, second jam pot (for larger batches), bubble remover tool, digital pH meter, storage shelving.
- Months 4+ (Nice to Have): Copper jam pan (if stainless steel proves too slow), induction burner, labeling equipment, additional jar sizes, vacuum sealer for bulk fruit storage.
New vs Used Equipment
Jam production requires clean equipment, but not all items need to be new. Your choices here affect both startup cost and safety.
Buy new: Mason jars (used jars may have hairline cracks that fail under pressure), lids (single-use—never reuse), thermometers (accuracy degrades over time), and anything that touches the finished jam during processing. Food safety regulations often require new equipment for commercial kitchens anyway.
Safe to buy used: Large pots, canners, cooling racks, colanders, and storage shelving. Check used pots carefully for dents, warping, or discoloration inside (can indicate previous damage). Inspect used canners for rust or damage to the rack. Copper jam pans hold their value and perform better when older—generations-old copper pans are prized because they conduct heat so evenly.
Buying used equipment from restaurant supply stores, estate sales, or farmers market vendors can cut equipment costs by 30-50%. Local jam makers often sell their extra equipment when they scale up or retire.
Where to Buy
- Amazon: Fastest for specialty items and bulk jar orders. Good for comparing brands and reading reviews from other jam makers.
- Restaurant supply stores: Significantly cheaper for large pots, canners, and commercial shelving. Ask if they offer food service discounts.
- Local farm supply or canning stores: Staff often have hands-on experience with equipment. They carry specialty items like copper jam pans and can advise on sizing.
- Estate sales and online marketplaces: Copper jam pans, vintage canners, and large commercial pots appear regularly at lower prices.
- Used restaurant equipment suppliers: When restaurants close or upgrade, equipment sells at steep discounts. Check Craigslist, Facebook Marketplace, and local restaurant liquidators.
- Agricultural extension offices: Many provide lists of approved equipment suppliers and sometimes negotiate group discounts.
