That's ASDA @ £1 per kilo for the yoghurt. Sounds as though Tesco is cheaper on the UHT though!
I've been buying their own brand for £1 per 500g, so was looking if I could 'brew' my own for less when I came across the Lancashire Farms cost.
Anyhow when prices flip the other way again I'll give it a go if my Inkbird and and immersion heater are free at the time...
Well the prices
have flipped in ASDA - the Lancashire Farms yoghurt which was £1 per kilo is now £1.80, and a litre of UHT milk is £1.15, so have now made a few batches.
Clean an empty Lancashire Farms tub and sanitise with StarSan. Scoop a desert spoon from a tub of bought yoghurt into the tub, add a bit of milk to thin it down, stirring with a sanitised spoon to mix it into a thin paste. Then add the rest of the milk (1L) and put the lid on.
Put the tub in the slow cooker, and fill with water to just below the top of the tub.
Pop the Inkbird probe under the pot so the wire curls up the other side and holds the probe mid-water. Set the temp to 43C, slow cooker on 'low', lid on, and leave it for 8 hours.
Job done.
It's not quite as 'tangy' as the original, but still good if not doing a side-by-side comparison.
I've done this for one 'second generation' using a home made batch as the starter, but find I get better results if I make 2 batches from the bought stuff up-front, and it keeps for a couple of weeks.
