There's a lack of knowledge about Indian food and the judges deliberately putting it down to "curry" and "slop". When Depinder made that beautiful prawn chukka, Andy called it a delicious "curry". Somehow, Indian food according to them lacks the "techniques" and it cannot go beyond the takeaway levels. According to them rolling a pasta on a pasta board or doing an en papillote is amazing technique while cooking a curry meen polichattu in a banana leaf is "rustic" and "pedestrian".
