Although Atlantic bonito (Sarda sarda Bloch, 1793) has a short fishing season compared to other common commercial species, it is stand out with its favourable aspects such as nutrient-rich lipid/protein composition, high-ratio meat yield and specific taste. Bonito fish are commonly consumed fresh, but also it can be preserved with dry salting or brine methods to produce traditional salted bonito (lakerda). However, gravlax is a high-valued gastronomic product which is made from salmon with dill (Anethum graveolens) in principle, hereby gravlax curing method that can be applied to different fish species and aromatic herbs. The aim of the study was to determine the characteristics such as consumers’ taste preferences, nutritional composition, colour and texture of bonito gravlax made with dill and garden cress (Lepidium sativum). The usage of dill or garden cress did not affect the crude protein values (p > 0.05). The moisture loss of group A (with dill) was higher than group B (with garden cress) (p < 0.05). The colour results proved that using garden cress instead of dill in bonito gravlax reduces the reddishness whereas increase the yellowish colour. ΔE (total colour difference indicates) was determined that the using of garden cress was more effective on the colour change of raw fish. Also, usage of the herbs in gravlax processing were affected these parameters and it may cause to change on fish texture. According to sensory analysis made by panellists showed that the aroma and salty taste of the two groups were found to be different. On the other hand, the general acceptability results of the groups were found to be similar.
