A canning funnel is a short, wide-mouthed funnel designed specifically to fit neatly into mason jars and other preserving jars. Unlike a standard funnel, it has a much larger opening and a short neck so that thick foods—such as jam, tomato sauce, pickles, or broth—can pass through easily. The tool creates a clean pathway from pot to jar, making it easy to fill jars quickly while keeping the rim clean, which is essential for proper sealing during canning.
Function
The primary function of a canning funnel is clean, efficient jar filling. Its wide opening accommodates chunky foods and thick liquids, while its rim-sized base sits securely on the mouth of the jar. This prevents spills and keeps food from touching the jar rim, which is important because residue on the rim can prevent a lid from sealing during water-bath or pressure canning.
In everyday cooking, the funnel is also useful for:
- Transferring simple syrup, broth, or sauces into jars
- Filling bottles with infused oils or vinegars
- Moving dry goods like rice, beans, or flour into storage containers
Origin Story
The canning funnel emerged alongside the rise of home food preservation in the 19th century. When John Landis Mason patented the Mason jar in 1858, home canning quickly became widespread across North America and Europe. As preserving fruits, vegetables, and sauces became a routine household activity, specialized tools evolved to make the process cleaner and safer.
Wide-mouth funnels appeared in kitchen catalogs by the late 1800s and early 1900s, often sold alongside jar lifters, ladles, and tongs in early “canning kits.” While no single inventor is credited with the canning funnel itself, it grew organically from the needs of home preservers working with Mason jars and similar containers.
Why Everyone Should Have One
A canning funnel is one of those deceptively simple kitchen tools that solves a surprisingly common problem: getting food into containers without making a mess.
Reasons it earns a place in almost any kitchen:
- Cleaner jar filling: Prevents sticky rims and spilled liquids
- Handles thick foods: Much better than a narrow funnel
- Speeds up prep: Useful for batch cooking and storage
- Inexpensive and durable: Often made from stainless steel or sturdy plastic
- Versatile: Works for liquids, sauces, grains, and dry goods
Even if you never preserve food, a canning funnel is incredibly helpful for transferring homemade simple syrups, stocks, salad dressings, or pickles into jars.
How Different Food Voices Might Describe It
Christopher Kimball (America’s Test Kitchen / Milk Street)
He would likely praise it as a practical, purpose-built tool: simple, inexpensive, and engineered to solve a specific kitchen problem—keeping jar rims clean so preserves seal properly.
J. Kenji López-Alt
Kenji would emphasize the mechanics and efficiency. He’d note that the funnel minimizes mess and contamination during transfers, which matters for both food safety and workflow when cooking in batches.
Anthony Bourdain
Bourdain might frame it as one of those humble tools that separates a chaotic kitchen from a competent one: not glamorous, but indispensable when you’re pouring hot sauce or stock into jars without covering the counter in sticky disaster.
Bon Appétit Magazine
Bon Appétit would likely call it a “low-cost, high-impact kitchen upgrade”—the kind of tool that instantly makes preserving, bottling sauces, or storing pantry staples feel more organized and professional.
What Else You Should Know
- Two sizes exist: funnels sized for regular-mouth and wide-mouth mason jars.
- Materials: common versions are plastic (often heat-resistant) or stainless steel.
- Short neck design: prevents air locks when filling thick foods.
- Dishwasher safe: most models clean easily.
- Many home preservers consider it part of the core canning toolkit, alongside jar lifters, bubble removers, and ladles.
Bottom line: the canning funnel is a small, inexpensive tool that dramatically improves the process of filling jars—whether you’re preserving tomatoes, storing dry goods, or pouring freshly made simple syrup into a mason jar.
