Lactalis is targeting home cooks with the extension of its Seriously Strong brand into chilled cheese sauce.

The sauce - stocked in cheese aisles - debuted in Waitrose last week, was stocked in Tesco this week, and will be available in Asda, Morrisons, Budgens, Spar and Nisa stores from next month.

Targeted at dishes such as fish pie and gratin bakes, Lactalis claims the sauce (rsp: £2.49 for a 250g tub) has a far higher average cheese content, at 44%, than competing cheese sauces, which average 14%.

Research (carried out in November last year by Stratégir) had shown that of 206 consumers asked, 75% agreed that it tasted like a homemade cheese sauce, Lactalis claimed.
