If using whole dried red chilies, break them open and shake out the seeds to remove most of them — this moderates the heat level similarly to deseeding a fresh jalapeño. The dried flesh and skin contribute the complex, fruity, slightly smoky depth of the dried chili without the concentrated seed capsaicin making the sauce aggressively hot. Tear or roughly break the deseeded dried chilies into smaller pieces — approximately 2–3cm — so the food processor can work them down evenly during blending. If using chili flakes, they can be added directly without any preparation. The choice between whole dried chilies and flakes is primarily a matter of what is available. Whole dried chilies — ancho, guajillo, New Mexico, or any mild-to-medium dried red chili — produce a more complex, fruitier, deeper heat with specific aromatic characteristics that flakes lack. Chili flakes are more consistent in heat level and widely available, producing a clean, direct heat without the specific character of a particular dried chili variety. Both are entirely valid.

Smash the three garlic cloves with the flat side of a knife — a firm press that opens each clove without fully flattening it. Smashing produces even garlic distribution during processing without the sharp, concentrated pockets that whole cloves can leave. Wash the cilantro bunch under cold running water and shake dry. The stems are included — the thin upper stems of cilantro hold the same aromatic compounds as the leaves and contribute herb intensity rather than texture in a blended sauce. Only the very lowest, thickest hollow base stems should be discarded. Zest the half lime before juicing it, taking only the outermost coloured layer and avoiding the white pith. Juice the same half lime after zesting.

Add all the ingredients to the food processor in the following order: the prepared dried chili pieces or flakes, the smashed garlic cloves, the cilantro with stems, the ground cumin, the ground coriander, the lime juice, the lime zest, and the olive oil. Begin processing using the pulse technique — 5 seconds on, 2 seconds off, repeating the cycle. The pulse approach is the defining technique decision for both zhoug versions. Continuous blending at high speed produces a smooth, uniform paste that loses the coarse, rustic texture that gives zhoug its character and the slight visual distinction between herb pieces, chili, and oil that makes it recognisable. Pulsing gives you control over the stopping point — assess the texture after every 2–3 pulse cycles and stop when the sauce is smooth overall but still has visible small pieces of cilantro and chili distributed throughout. The red zhoug's texture should be slightly looser and finer than the green version because the dried chili breaks down more completely than fresh jalapeño — the result is a sauce that looks more like a thick, herb-flecked paste than the coarser green version. After approximately 6–8 pulse cycles, check the consistency. If the processor is struggling to move the mixture evenly, add additional olive oil one tablespoon at a time and pulse briefly after each addition until the sauce moves fluidly.

Stop the processor and taste carefully, keeping the heat development characteristic specifically in mind. Evaluate acidity, salt, and heat separately. Acidity: if the sauce tastes heavy or the citrus brightness is absent, add an additional small squeeze of lime juice. Salt: if the sauce tastes flat despite having all ingredients, add salt in small pinches, processing briefly between additions. Heat: if the chili warmth is not yet present, this may simply mean the capsaicin has not yet fully migrated into the olive oil — before adding more chili, allow the sauce to rest for 5 minutes and taste again. If after resting it still seems too mild, add a small additional amount of chili flakes — ¼ tsp at a time — and pulse briefly. Earthiness: the cumin's warm, earthy depth deepens significantly in the olive oil over the first 15–30 minutes after making, just as it does with the green version. Do not adjust the cumin immediately after blending — wait and taste again before the sauce is served.

Transfer the blended red zhoug to a serving bowl or storage jar and allow it to rest for a minimum of 15–30 minutes before serving. This resting period is more important for red zhoug than for the green version specifically because of the dried chili's progressive heat release into the olive oil. A sauce tasted and calibrated at zero minutes and then served at 30 minutes may be significantly hotter than expected — always allow the rest and taste one final time immediately before serving to confirm the heat level is at the right point. During the rest the cumin also blooms further into the oil, the garlic's sharpness mellows slightly, and all the flavour components begin to integrate into a more cohesive, unified sauce.

Transfer to a small serving bowl or pour into a small jar for table service. Red zhoug does not need garnish — its deep brick-red to dark reddish-brown colour with flecks of green cilantro visible throughout is its visual identity and requires no addition. Serve alongside warm Homemade Lavash or Fresh Pita Flatbread, drizzle over Classic Hummus or Authentic Labneh, or spoon alongside any grilled protein.
