PROPER, the UK’s fastest-growing major snack brand, is bringing the heat to the snack aisle with the launch of PROPER House Hot Sauce Lentil Chips.
Heat is having a moment - from celebrity bottles to viral hot sauce challenges - and it’s showing up in snacking in a big way. Spicy CSN (Crisps, Snacks & Nuts) flavours are now worth £528m in the UK and growing +3% year on year, accounting for 16% of CSN sharing sales and now growing 4.4x faster than the category.
PROPER doesn’t do off-the-shelf heat. That’s why the team crafted a bespoke House Hot Sauce in-house with Development Chef Ed, who created the original PROPER lentil chip five years ago.
The result is a mighty lentil chip with a controlled heat and a tangy finish that keeps you coming back for more, all brought to life in bold vibrant packs that bring feminine edge to an otherwise masculine space.
PROPER House Hot Sauce Chips are made with natural flavourings, are gluten free, and come in at under 100kcal per serve. The new chips are available in both Sharing bags and Price Marked Packs, launching in Tesco stores on 20th January, with wider retailers from March.
PMP lands in Nisa, Costcutter, Spar, and Dhamecha from 2nd February. The release will be backed by the latest iteration of the Practice PROPER Snacking campaign, featured across digital, sampling and in-store touchpoints.
The launch builds on PROPER’s strong track record of flavour-first innovation, with PROPERCHIPS being the category’s most successful innovation in the past five years, generating over £30m RSV and +21% year-on-year growth. Recent launches, including All the Cheese Lentil Chips and Prawn Cocktail Lentil Chips, have delivered over £3.2m RSV, with Prawn Cocktail driving 54% incremental sales to total CSN.
Sandie Dilger, Chief Marketing Officer at PROPER SNACKS, commented: “Our Chips range keeps going from strength to strength as more people look for non-potato alternatives to traditional crisps, so it felt like the right time to bring a properly standout spicy flavour into the line-up.
"We’re hot sauce obsessed in the office, so we jumped at the chance to create our very own House Hot Sauce, and then work out how to translate that unique flavour kick onto a chip.
"Prawn Cocktail was our breakout launch of 2025 and it still flies off the shelves so fast we can barely get our hands on it…but I wouldn’t be surprised if this tops it. My money is on this one for the cult spicy hit of 2026.”
PROPER SNACKS – home of PROPER and Eat Real – is now a top five snacking manufacturer, growing 10x faster than the category in the past 12 weeks[3]. More than 1 in 5 households buy a PROPER SNACKS product every year[4], with six packs sold every second[5] - PROPER SNACKS has now become a staple in the nation’s weekly shop.
