Ingredients
Method
Build the sauce base (this is your service engine)
- Heat oil in a large pot or rondeau on medium-high.
- Add sliced onions and cook 8–10 min until softened and lightly golden at edges.
- Add pepper strips, cook 4–5 min to soften slightly but keep some texture.
- Add tomato paste, cook out 2–3 min (important: remove raw taste).
- Add ketchup + passata, stir until homogeneous.
- Add stock, bring to a steady simmer.
- Season: paprika(s), pepper, curry (optional), Worcestershire, vinegar, sugar, salt (start lower).
- Simmer 15–20 min, stirring occasionally to prevent catching.
- Consistency target: thick enough to cling to skewers and fries, not watery.
- If too thin after simmering, add cornflour slurry gradually while simmering, until it nappes the back of a spoon.
Prep and build skewers (batch)
- Cut Frankfurter into 4–5 cm chunks (bigger looks more “Imbiss” and holds better in sauce).
- Cut onions into petals and peppers into 2–3 cm squares for threading.
- Toss Frankfurter pieces lightly with oil, salt, pepper, smoked paprika (and optional garlic powder).
- Assemble skewers: Frankfurter → onion → pepper → repeat (4–5 sausage chunks per skewer).
- Use metal skewers for service; soaked bamboo works for home or events.
Sear/grill the skewers for flavour (don’t skip)
- Goal: browning + a little char. This creates the “stall” taste.
- Plancha / flat top: 2–3 min per side
- Chargrill: 3–5 min total, turning
- Heavy pan: 6–8 min total, in batches
- You are not “cooking from raw” here—Frankfurter is ready-to-eat—so you’re building colour and flavour.
Finish in sauce (the Imbiss signature)
- Lay seared skewers into the simmering sauce (single layer if possible, then stack).
- Simmer gently 6–10 min so the skewers are fully hot and sauce clings.
- Hold at ≥63°C for service.
Service options:
- Fastest: hold skewers in sauce; plate/box to order.
- Best texture: hold sauce hot, keep skewers warm/dry, dip/finish 2–3 min in sauce to order.
