Patchy white mold is usually cosmetic, not a defect — the protective effect scales with coverage, so a salami that’s 60% bloomed still gets most of the benefit, it just looks less finished than a fully-coated one. Uneven coverage only becomes a real problem in two cases: when the bald areas invite other molds to […]
Collagen casings resist white mould because their surface is smooth, processed, and often treated in a way that gives Penicillium nalgiovense nothing to grip. Natural casings are a porous protein membrane the mould can root into; extruded collagen is a uniform film that frequently stays bald no matter how carefully you spray it. If your […]
Yes — spreadable salami like ‘nduja and sobrasada is safe when it is made by the rules: the correct curing salt (Cure #2 for a long ferment and dry), a starter culture that drops the pH below 5.3, salt around 2.75%, a controlled warm-humid fermentation, and enough drying to pull the water activity down. Safety […]
Repack leftover natural casings in plenty of plain non-iodised salt, seal them airtight, and refrigerate — stored that way they keep for a year or more. Salt drops the water activity so low that spoilage bacteria simply cannot function. The enemies of stored casings are not time but drying out, moisture creeping back in, and […]
Air pockets in salami come from air folded into the farce during mixing and stuffing, and the fix is a two-part habit: prick and press every pocket out at the stuffer, then prick again after fermentation when the casing tightens. Air pockets are not cosmetic. A trapped void holds oxygen against the fat, which oxidises […]
Yes, you can reuse the white mold from a finished salami to inoculate your next batch — cut a coin of well-bloomed casing, blend it into a little dechlorinated water to release the spores, strain out the solids, and spray that slurry onto the fresh pieces exactly as you’d apply a bought culture. Once my […]
‘Nduja is done when it has lost about 25–30% of its stuffed weight — not after a set number of days. That soft-spread endpoint takes roughly 2–3 weeks for a narrow piece and 4–8 weeks for a fat beef bung, because diameter, humidity, and your chamber all change the pace. Weight loss is the honest […]
Casings burst for three reasons, almost always in this order: the meat is too warm and smears, the stuffing pressure is uneven or too fast, or the casing was under-soaked and brittle. Keep the farce below 4 °C, fill slowly and steadily with no trapped air, match the horn to the casing, and hydrate the casing […]
Sobrasada is a soft, spreadable Mallorcan cured sausage built on fatty pork and a heavy dose of sweet pimentón paprika — roughly 4–6% of the meat weight — salted at about 2.75%, cured with Cure #2, fermented to drop the pH below 5.3, then dried to a soft-spread endpoint around 25–30% weight loss. It is […]
To spray Penicillium mold culture on salami for even coverage, rehydrate the culture in non-chlorinated water, let it wake up for a few hours, then mist a fine, uniform coat over every surface of the casing within about a day of stuffing — while the chamber sits humid, around 85% RH. Chlorine kills the spores, […]
