A creamy, buttery flavor or aroma with a pleasant note, reminiscent of bread is imparted to foodstuffs by heating them under controlled conditions in the presence of Amadori rearrangement compounds, having a melting point below 170 DEG C, of 6-deoxy-aldohexoses, such as e.g. rhamnose, and alpha-amino acids, such as e.g. proline. Frying and cooking fats, including margarine, comprising these Amadori compounds are also described.
