Using Vegetarian Gel

I love Delia 's recipes but a number use gelatine. As a vegetarian this is not an option. I would like to make the set cheesecakes in this weeks cake of the week.Would it be possible to include the amount of vegetarian setting agent that is the equivalent to the amount of gelatine recommended in the recipes? It would be good if this was in all of her recipes using gelatine! I appreciate that you would not want to be recommending a specific setting agent by name, but an indication of how much needs to be set would be helpful.Thank you
