Tonight's menu is a credit crunch-proof delicious three-course meal for four people for less than a tenner: a starter of minted pea and watercress veloute; a main course of Gordon's classic lasagna al forno; and for dessert, lemon and lime syllabub. Proof positive that delicious food really doesn't have to cost a fortune. No matter how rarely you cook, if you buy the ingredients, get all your utensils ready, and then follow Gordon's instructions live on the show, you can create a fantastic meal for four people (online guides, and ingredient and utensil lists can all be found at www.channel4.com/food). To prove that point, producers have invited on Johnny Vegas to accompany Gordon on his cookalong this evening.
