Apparatus ( 10 ) and methods are disclosed where plastic extrudable food product is provided such as by an extruder or pump and is combined with another food product without intermixing to form a complexly patterned food product, such as by a pattern forming die ( 20 ). The cross-sectional area of the patterned food product is reduced from an inlet end ( 34 ) to an outlet end ( 36 ) by a factor of 4:1 to as much as 50:1 at an average convergence angle of 5 to 65° while maintaining the cross-sectional pattern to form a reduced cross-sectional patterned food product, and then is extruded through a die port having an opening equal to the reduced cross-sectional area to form a complexly patterned extrudate. |
