A Kickstarter campaign to fund slices of tomato sauce has seen the amount pledged to back it double to more than $30,000 (£21,400).

Slice of Sauce first came about when Emily Williams, whose father ran a restaurant in Michigan, US, was practising an old family recipe.

An attempt at creating a dried version of her dad's BBQ sauce - intended to save on vegetables wasted in the cooking process - led her to develop the dried ketchup, which eventually became the finished Slice of Sauce product.

Ms Williams gave up her office job to create the solid ketchup, teaming up with her former boss Thac Lecong to form the company.

Described as "all natural, no mess and flavour packed", the unexpected concept also boasts sustainable packaging, with the packs of eight portions not being individually wrapped.


The Kickstarter page says the dried product does not have to be kept in the fridge, and promises "a perfectly portioned bite every time".

Ingredients include vine-ripened tomato purée, distilled vinegar, cane sugar, salt, onion powder and garlic.

Now they have smashed their fundraising goal, the aim is to create the slices by hand in a state-of-the-art manufacturing facility in Brooklyn, New York.

The company hope the slices will be available online and at selected speciality outlets by June.

Co-founder Mr Lecong said: "It's going to be like the first man on the moon, except this time the moon is a sandwich."

Earlier this month Mayochup - a pre-made mixture of ketchup and mayonnaise - split opinion worldwide after Heinz asked US consumers whether they would like to see the condiment stocked in supermarkets.

Many felt the hybrid sauce, which is already available in parts of the Middle East, was just over-hyped Marie Rose sauce while others thought the combination was ingenious.
