Double Oak Smoked. Dr Trouble Double Oak Smoked 125ml - Lemon Juice, Chilli Asafoetida Extract, Ginger powder, Garlic Powder dried Fenugreek, rock salt. Our flagship flavour... The chilli is hot-smoked over rare English Oak chips, and allowed to cool, and then smoked for a second time... lending the unique, and sweet smoky overtones that have made our sauce so popular. The chilli, lemon juice and spices are poured into custom blown glass sun flagons. These 30-litre flagons are placed in the hot African sun for up to 60 days. Each flagon gently stirred twice a day, encouraging the flavours to meld into a smooth and aromatic flavour, versatile for all food types.
