Peanut Rayu

White Mausu Peanut Rayu is the brand's signature product and a genuine cult favourite, a crispy chilli oil packed with roasted peanuts, sesame, and just the right amount of heat. Fried garlic is gently crisped, peanuts and sesame are roasted, and gochugaru (Korean chilli flake) and a house blend of chilli are added, with agave bringing sweetness and tamari the salt. The result is a perfectly balanced, umami-rich everyday sauce, not too spicy, endlessly versatile, and completely addictive.

White Mausu is a chilli oil company based in Dublin, Ireland, founded by two passionate cooks, Katie and Jasper, who met working in a Dublin cafe and bonded over a rayu made by a Japanese friend. With decades of combined cooking experience, they craft small batches of their signature jars to deliver restaurant-standard flavour at home. This peanut rayu is suitable for vegans.

True to its billing as a true everyday sauce, it has a rightful place alongside nearly every meal. Spoon it over eggs, vegetables, rice, and noodles, drizzle it on salads, use it on steaks, or reach for it during a fridge raid. Topped with a crispy fried egg or stirred through a stir-fry, it turns simple food into something special.
