Summary:
                    
A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.
                      Relatively low in protein, a single tablespoon of ginger contains 0.5 grams of protein, or about 1% of recommended daily values. [1]
 To get the adequate amount of protein with ginger alone, you will need 103 tablespoons of ginger (560 grams) for an average female, or 124 tablespoons of ginger for males. [4] That's over 1870 calories. Pairing ginger with a richer protein source is a good idea.

                    Proportionally, ginger does contain abundant amounts of 6 out of the nine essential amino acids.  However, ginger is a little short on leucine, lysine and methionine.[1]
To have adequate amounts of all nine essential amino acids with ginger alone, you will have to eat 179 tablespoons of ginger (966 grams) for an average person. [2]
That's about 73% more ginger to compensate for the lack of leucine, lysine and methionine, compared to the protein requirement alone.

                      Low in protein, carrot is high in leucine, lysine and methionine,  which is complementary to ginger. 
A ratio of 3.3 tablespoons of ginger (18g) and 2.7 carrots (194g) creates a complete protein profile. In fact, any ratio of more than 11:1 of carrot to ginger will be complete.

                      Dijon mustard is a great source of protein, and  is high in leucine, lysine and methionine,  complementing the profile of ginger. 
For example, 5 tablespoons of ginger (27g) and 3.8 tablespoons of dijon mustard (23g) make a complete amino acids profile. In fact, any ratio of more than 0.8:1 of dijon mustard to ginger will be complete.

                      Sour cream is a reasonable source of supplementary protein, and  is high in leucine, lysine and methionine,  complementing the profile of ginger. 
For example, 10 tablespoons of ginger (54g) and 0.4 cup of sour cream (76g) make a complete amino acids profile. In fact, any ratio of more than 1.4:1 of sour cream to ginger will be complete.
