Disclosed are apparatus (10) for making a complexly patterned extrudate. The apparatus (10) includes a food cooker extruder (12) for providing at least one extrudable food product, at least one food color supply (18), a pattern forming die (20) for mixing the food color and extrudate food product to form a complexly patterned food product, a reducing passageway for reducing the cross sectional area of the patterned dough from an inlet end (34) to outlet end (36) of at least 50:1 at an average convergence angle of .ltoreq.45.degree. and an extruder exit port at the discharge end of the reducing passageway. The methods comprise the steps of: providing a plastic extrudable food mass; providing at least one color; mixing the food mass and color to form an organized complexly patterned food dough having an initial cross sectional area; reducing the initial cross sectional area by a factor of at least 50:1 with an average convergence angle of .ltoreq.45.degree. while maintaining the cross sectional pattern to form a reduced cross sectional patterned dough, and extruding the reduced cross sectional dough through a die port having an opening of equal to the reduced cross sectional area to form a complexly patterned extrudate.

[ What is claimed is:] [1.] A method for preparing a food product having at least two exposed colors with improved detail resolution comprising:directing a first food mass through a passageway;adding a second food mass, contrasting in color to the first food mass, into the passageway;integrating the first and second food masses to impart a complex pattern of the second food mass to the first food mass, thereby creating a third food mass having an initial cross-sectional area defined by the passageway; anddirecting the third food mass through an acutely converging portion of the passageway to reduce the initial cross-sectional area of the third food mass by at least 4:1 while maintaining the complex pattern of the third food mass.
