Can i substitute sago with semolina in a plum pudding?

Sago is a starch extracted from the pith of various tropical palm stems, while semolina is a coarse flour made from durum wheat. Sago and semolina have different textures and nutritional properties, so they cannot be substituted for each other in a plum pudding. Sago is a glutinous starch that forms a translucent gel when cooked, while semolina is a granular flour that does not form a gel. Semolina also has a higher protein content than sago, which can affect the texture and flavor of the pudding.
