Sloe gin is traditionally made after the first frosts have 'bletted' the fruit, but we pick them earlier and put them in the freezer. Some recipes suggest adding sugar but we prefer it without.

It's easier to ferment first, which softens the flesh and makes it much easier for the stones to be removed. But you could take out the stones and it should still work.

It's been a great year for sloes, the hedgerows are packed with them. But you can make so much more than sloe gin with these wild fruit!

Just opened my first batch of salt-fermented sloes for this year. Follow this link for the #recipe: jeffollerton.co.uk/2020/10/03/r...?

Well, it's not a solution, but at least the results are pointing to the fact that a 10% threshold is not nearly enough.

I will consider forgiving all the Oirish nonsense in “House of Guinness” if it includes a two-episode mini-arc entirely about William Sealy Gosset and the origin of the t-test.

The conundrum we find everywhere.

Far too little for for the insects, but far too much for the farm lobby (the EU tried to go for 7%, paid for with subsidies, but has now pretty much abolished it, as did the UK as soon as it Brexited).

Scientist who works on #bees here, Mark: the short answer is, no, bees are not getting bigger. But bees do vary hugely in size, depending on the species, from just a few millimetres to several centimetres - see this graph from my book 'Pollinators & Pollination: Nature and Society' @rileyrouth.com

Urban habitats may not be supporting as many female #bees...

"Since females are the ones responsible for nest-building and and potentially #pollination, as they visit more flowers, this imbalance could have long-term effects on bee populations and the pollination services they provide."
