Denmark "recontacted" Greenland in 1721, while many Danes lived there, outside the conversion of the Inuits, there was little attempt to Danifying it before the post-War period.
What few people know is that while Greenland is relative shitty for agriculture, agriculture and forestry, they're possible. In the valley of southern greenland there exist a remnant of the original forests of Greenland, and agriculture is quite possible in them. You could establish agriculture based on potatoes, cabbage and grazing animals (barley wopuld likely only become possible in the late 20th century), quinoa can also theorectical grow on Greenland, but Danes lacked knowledge of the crop. Forestry could be spread in these valleys too, they're significant warmer than the coast.
So what if Denmark decided to use resources on establish some farms in these valley. It would ensure a local supply to the local Danish merchants and adminitrators, and also to the Inuit in starvation times. The result could be a more true integration of the Greenlandic west coast into Denmark, but we could also see increased mining and a more successful whaling industry in the late 18th century.
