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 date contains 0.4 grams of protein, or about 1% of recommended daily values. [1]
 To get the adequate amount of protein with dates alone, you will need 115 dates (2760 grams) for an average female, or 138 dates for males. [4] That's over 7650 calories, and a lot of date! Pairing date with a richer protein source is a good idea.

                    Proportionally, date does contain abundant amounts of 2 out of the nine essential amino acids.  However, date is a little short on isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan and valine.[1]
To have adequate amounts of all nine essential amino acids with date alone, you will have to eat 211 dates (5059 grams) for an average person. [2]
That's about 83% more date to compensate for the lack of isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan and valine, compared to the protein requirement alone.

                      Low in protein, carrot is high in isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan and valine,  which is complementary to date. 
A ratio of 3.3 dates (80g) and 2.6 carrots (189g) creates a complete protein profile. In fact, any ratio of more than 2.4:1 of carrot to date will be complete.

For example, 10 dates (240g) and 0.4 cup of pumpkin seeds (24g) make a complete amino acids profile. The entire range to create a complete protein are ratios of 1:0.1 to 1:10 for date to pumpkin seed by weight.

                      Sour cream is a reasonable source of supplementary protein, and  is high in isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan and valine,  complementing the profile of date. 
For example, 10 dates (240g) and 0.4 cup of sour cream (74g) make a complete amino acids profile. The entire range to create a complete protein are ratios of 1:0.31 to 1:31 for date to sour cream by weight.
