im making a 'pig roast' cake for a pig roast this weekend. i was originally plnning to make it more 'cartoony' but now im thinking i want to go with the more realistic approach. if i dont havea n airbrush, how can i get the roasted/glazed look to it? do you think i can get away with using brown fondant, or will that be too dark? or should i tint white fondant with brown gel color since that would be lighter? or other suggestions/tips/ideas??? please & thank you =)

Use coloured corn syrup or coloured piping gel. Just brush it on (you can even use a wide pastry brush).
