Soften the baby sweetcorn along with a little turmeric and then cook in the chicken stock.
Cut the carrot and beetroot into slices and marinate them in the vinegar plus sugar to achieve a sweet-sour flavour. Deep-fry the cubes until crispy. For the sauce, soften the shallot, then add the mustard and the red wine. Reduce and then add the fond.
