Sardines have a distinctive, somewhat strong flavor that some people find off-putting initially. Start by incorporating them in small amounts into familiar dishes. For example, mash them into pasta sauce, add them to salads, or use them as a topping for crackers with cream cheese or avocado.
Experiment with different preparations and flavor combinations. Lemon juice, hot sauce, or herbs like parsley and dill can help balance the taste of sardines. You can also find sardines packed in various sauces, such as tomato sauce or mustard, which can make them more palatable. Over time, you may find yourself developing a taste for these nutrient-rich fish.
What is the difference between canned sardines packed in oil versus water, and which is healthier?
Canned sardines packed in oil tend to be higher in calories and fat than those packed in water. The oil can add a richer flavor and texture, but it also increases the overall fat content, including saturated fat depending on the type of oil used. However, some oil-packed sardines may be beneficial because the oil helps preserve the omega-3 fatty acids.
Sardines packed in water are lower in calories and fat, making them a good option for those watching their weight or fat intake. While some omega-3s may leach into the water, they still retain a significant amount of these beneficial fats. Choose sardines packed in water if you’re concerned about sodium content, as they often have less sodium than those packed in brine or oil. Ultimately, the “healthier” option depends on individual dietary needs and preferences.
