2025 - What I harvested today

Veggie I add a squirt of lemon juice to the water otherwise  the apples go brown,  they still taste ok but look a bit off putting.  Next they go in  the salad spinner finally between 2 tea towels to get the pieces as dry as possible.

Pardon me fo posting on this thread but I have quite a few apples to harvest so I have just ordered an apple corer/peeler from B&Q online, with free delivery at £8.49 which wa the cheapest I could find? I know othes on this site have used them so look forward to using it to make use of this along with my dehydrator fo processing my apple rings.
My plan would be to fill a bowl with water and add lemon juice to stop 'rings' discolouring as I was going? How much lemon juice would I need to add?

Mods, please move this post to another relevant post if you are not happy with it being here?

I asked Bren the same question prevously - the answers "a squirt" .

Would that be a metric squirt or an imperial squirt then?

Half a teaspoon of citric acid might do as well, if you've got some.
