The purée is divided between 3 ramekins: on the right plain, in the centre with the stone, and on the left with a pinch of vitamin C.

Stage 4

Unfortunately the stone has had no effect.

Stage 5

The vitamin C, on the other hand, has acted as an effective anti-oxidant.

Conclusion

False: So there is no point leaving the avocado stone in the prepared dish. Vitamin C, and so the lemon juice added to guacamole is much more effective.

And to drink?

We'll prepare an avocado purée and share it between 3 ramekins: 1 plain, 1 with the avocado stone, 1 with a little vitamin C added. They will be left for several hours to see what happens to the different dishes of purée.

Thanks for doing this, been wondering if it's at all true. Now I understand it's the lemon juice I've been using, not the stone, that has kept my guacamole fresh :)
