Comfort food is food prepared traditionally that may have a nostalgic or sentimental appeal.[1] Comfort foods may be foods that have a nostalgic element either to an individual or a specific culture.[citation needed] Many comfort foods are flavorful and easily eaten, having soft consistencies.

One recent development, as chefs have explored the roots of American cuisine and tried to define it as a unique style, is the advent of fine dining comfort food restaurants that feature more careful cooking and presentation, higher quality and fresh organic ingredients, along with consequently higher prices.
