Heston Blumenthal&#x27;s edible garden. The dish consists of a mayonnaise type sauce, with olive ‘soil’ on top, into which you ‘plant’ the baby veg. The home cook says: &quot;There was nothing particularly difficult about it, but the olives took four hours to dry out to make the soil. We also couldn’t get hold of the cereal required to give the soil a bit of extra colour, so we added toasted pinenuts instead.&quot; An interesting dinner party dish.
