- Compatible with Presto, All-American and other standard canners
- Smooth surface is quick and easy to clean
- Flat, stable design helps prevent jar rattling and breakage

The FONLLAM 2-pack provides 11-inch stainless steel racks made for pressure canners, pressure cookers and water bath canners. They are built for home preservers who process jars regularly and need reliable jar support.
Each rack keeps jars elevated for even heat circulation and helps prevent rattling, cracking and direct contact with the canner bottom. The tiered design lets you stack a second layer, so you can process more pints or half pints in one batch.
Construction is solid stainless steel with a smooth, corrosion resistant finish that holds up to heat, water and acidity. At 11 inches wide with a low profile, the racks sit flat and fit popular Presto and All-American models well.
Fit is the main limitation, as you must measure your canner since smaller or oversized pots may not match the 11-inch size. The 8-pound capacity per rack is ample for standard jars but requires care when double stacking heavy quart jars.
Overall, this is a practical, durable upgrade for anyone serious about safe home canning. The two-pack format adds real value for batch processing, separating layers or outfitting two canners at once.

It is bulky at over 20 pounds and 16 inches tall, so you will need dedicated counter and storage space. Boiling water canning is limited to half-pints and pints, and electric heating takes patience compared to a powerful gas burner.
For safe, set and forget canning of vegetables, meat, jams and salsa, the Presto Precise is hard to beat. If you want USDA-compliant automation with strong safety protection, this is the home canning upgrade worth considering.
Capacity: 12 quarts, holds 10 half-pints, 8 pints, 5 quarts for pressure canning. Boiling water method for half-pints and pints only.

Buying Guide: What Matters for a First Mushroom Grow
We assessed seal reliability, usable capacity, heat compatibility, and monotub workflow fit across all ten picks. Our focus was beginner success with grain jars, spawn bags, and agar pours, not general food canning. Use these four criteria to match a canner to your kitchen, your batch size, and your comfort level.
If you are unsure about safety ratings, materials, or gauge accuracy, review how to tell if a pressure canner is safe for spawn before you buy. A clear checklist helps you avoid thin walls, unclear pressure control, or missing racks. Your first grow should feel controlled and repeatable.
Seal Design and Sterile Consistency
All American 1930 models use an exclusive metal-to-metal sealing system with positive action clamping locks. You get a steam-tight seal without gaskets to replace, plus a precision machined regulator weight and easy-to-read steam gauge. For mushroom work, that means steady 15 PSI holds for grain without surprise leaks.
Presto models like the Presto 01781 23-Quart Pressure Canner and Cooker and Presto 01784 23-Quart Induction Compatible use a more traditional sealing approach with a deluxe pressure dial gauge. You will want to keep the rim clean, seat the lid carefully, and watch the gauge during venting and processing. Both styles can deliver clean spawn when you follow a proven cycle time.
Capacity for Grain Jars and Spawn Bags
Size determines how many jars you sterilize per run and how often you repeat. The All American 1930: 10.5qt Pressure Cooker/Canner holds approximately 7 pint jars or 4 quart jars, ideal for small trial batches. The All American 1930: 15.5qt Pressure Cooker/Canner steps up to about 10 pints or 7 quarts, a sweet spot for many first grows.
For bulk monotub plans, the All American 1930: 21.5qt Pressure Cooker/Canner holds about 19 pints or 7 quarts, while the All American 1930: 41.5qt Pressure Cooker/Canner handles about 32 pints or 19 quarts. Presto 23-quart options fit 20 pints, 7 quarts, or 26 half-pints. Pair your choice with a nutrient rich bulk substrate for oyster mushrooms with nutrient rich bulk substrate for oyster mushrooms to plan spawn ratios.
Stove Compatibility and Pressure Control
Check your burner before you commit. Most All American 1930 canners suit gas, electric, or flat top stoves and feature a satin finish, sturdy phenolic top handle, and double-thickness edges for durability. The Presto 01784 23-Quart Induction Compatible adds a stainless steel-clad base for induction ranges, gas, electric, and smooth tops, plus an air vent and cover lock for added security.
If dials and weights feel intimidating, the Presto 02144 12-Quart Digital Pressure Canner offers a guided digital interface with LED stage icons and automated temperature control. Always follow the manufacturer’s own instructions for your specific unit, never leave it unattended while pressurized, and let the pressure release naturally before opening the lid. Steady heat-up, proper venting, and calm cool-down protect both you and your cultures.
Workflow Fit, Racks and Long Term Value
Beginner success often comes down to small details like rack height and jar spacing. The 2Pack Stainless Steel Canner Rack gives you tiered storage, corrosion resistant steel, and compatibility with Presto and All-American vessels. You can stack pints safely, improve steam circulation, and reduce cracked glass during long grain cycles.
Think about cleaning and storage too. A smooth satin interior wipes down quickly after sugary agar or grain boil-over, and color options like Onyx Black and Candy Red on the All American 1930 21.5qt Pressure Cooker/Canner help you spot your unit in a busy kitchen. Combine good sterilization with a clean monotub liner with clean monotub liner practices for easier harvests and faster tub resets.
Final Thoughts
For a balanced first setup choose All American 1930: 15.5qt Pressure Cooker/Canner for gasket-free reliability in a manageable size, while Presto 01781 23-Quart Pressure Canner and Cooker suits beginners who want extra-large batch capacity with familiar dial control.
Frequently Asked Questions
What size All American canner is right for a first mushroom grow?
Most beginners do well with 15.5qt to 21.5qt because you can process enough quart jars for one or two monotubs without a huge learning curve. The 10.5qt size works if space is tight and you prefer small, frequent runs. Choose the 41.5qt only if you already plan large or shared batches in 2026.
Can I use a Presto canner instead of an All American for grain spawn?
Yes, many first-time growers succeed with Presto 23-quart models for rye, millet, and wild bird seed. They offer large Mason jar capacity, clear gauges, and a canning rack plus instruction book to guide your process. See the detailed Presto 23-quart pressure canner guide to compare features and workflow tips for 2026.
How many grain jars fit in a 21.5qt canner for monotub spawn?
A 21.5qt vessel typically holds about 19 pints or 7 quarts, enough to inoculate a medium monotub with extra jars as backup. Wide-mouth quarts colonize evenly and pour cleanly into bulk substrate. Always leave headspace, loosen lids or use filter discs as directed, and avoid overpacking.
Do I need a separate rack for sterilizing mushroom jars?
A rack is strongly recommended because it lifts jars off direct heat and promotes even steam flow. The included Presto rack works well, and the stainless two-pack adds tiered space for pints in taller canners. In 2026 growers also pair racks with foil-covered lids and proper cool-down for cleaner results and fewer cracks.
Browse more picks in our Sterilization & Pasteurization category, or see our related guide on Presto 8-Quart Pressure Cooker for Mushrooms 2026 Guide.
These picks are not a good fit if you only ever use pre-sterilized, ready-to-use grow bags; a pressure cooker or canner is aimed at growers making their own grain spawn or bulk substrate from scratch.
