When it comes to making marmalade, some parents might think they're following the "proper" method by warming jars and using protective wraps like circles of baking paper or cellophane. However, a local family's experience suggests that this approach may not be as crucial as everyone thinks.
Dagna, from Berkhamsted in Hertfordshire, and her son both make marmalade with the same ingredients but vastly different techniques. The result? No mould on their jars whatsoever. Camilla Wynne, an expert preserver and author of "All That Crumbs Allow", explains that the high sugar content in marmalade makes it difficult for bacteria to grow. "Mould needs water to thrive," she says. "Sugar binds to water, so this makes it hard for mould to develop."
The only issue Dagna's son has faced is with his original recipe's reduced sugar levels, which caused the growth of unwanted microorganisms. A former student also had trouble due to the same reason.
In contrast, author Pam Corbin stresses that using modern food-grade lids, equipped with a wax seal inside, is far more effective than protective wraps. "Nowadays, our lids are much safer," she says. It's essential to use only clean new lids to ensure proper sealing and avoid potential contamination.
When it comes to jars themselves, opinions vary. Some experts like Wynne insist that warming them is necessary to prevent mould or yeast from forming. However, Corbin disagrees, provided the jars are thoroughly cleaned. "We've done things this way for generations," she notes, "so if it makes people happy, let's keep doing it."
A more pressing concern is overcooking marmalade, according to Corbin. When made incorrectly, the result can be an unpleasantly sweet taste reminiscent of barley sugar.
So how do you know when your marmalade is done? Wynne says look for light white bubbles and a glossy finish on top. Finally, always fill those jars to the brim, as any air gaps can introduce contaminants.
