Physiologist’s family favourite recipe #1
This recipe hits two physiological targets. Carrots supply vital beta-carotene which is converted to Vitamin A, important in vision, and capsaicin in
the chillies to stimulate TRPV1 receptors, which gives the dish that extra zing. The induced salivary secretion seems mainly to be mediated via
parasympathetic, cholinergic reflex mechanisms. Note that painful exposures to capsaicin-containing peppers are among the most common
plant-related exposures presented to poison centres.

          Carrot Chilli for the Discerning Vegetarian Physiologist – by Rachel Tribe
                         Feeds six hungry people (plus leftovers). Preparation time 20 minutes, cooking time 30 minutes.

Ingredients                                                                  Technique
- 1 tablespoon of olive oil                                                  1. In a large wok, heat up oil and gently fry the chopped onion until

- 2 cloves of garlic -crushed                                                   ginger and cook until fragrant (~ two minutes).
- 2 teaspoons of grated fresh ginger
- 1 teaspoon of cumin                                                        2. Add green chilli and grated carrots, followed by tinned tomatoes,

- 1 kg of carrots (grated using food processor - coarse setting)
- 1-2 small green chillies (seeds removed, finely diced)                     3. Then add ~ two thirds of the chopped coriander to the wok.
- 2 x 400g tins of kidney beans in chilli sauce
- 2 x 400g tins of chopped tomatoes                                          4. Simmer carrot chilli for ~ 30 minutes so the grated carrot is

- 50g bunch of fresh coriander (chopped, with one third of leaves
  set aside as garish when serving)                                          5. Cashew nuts and lime juice (plus remains of the coriander) can be
