How to choose fresh ingredients
How to choose fresh tomatoes
- Fresh tomatoes should have a bright red color, plump, shiny skin, and a faint characteristic tomato smell. Newly harvested tomatoes should have fresh stems tightly attached to the fruit. When cut in half, the seeds should be yellow and the flesh red, indicating ripe and delicious tomatoes.
- If you see tomatoes with scratched or bruised skin, or feel soft and mushy, they are overripe and may be spoiled inside. Moreover, if the tomatoes still have green skin, you should let them ripen for a few days, as green tomatoes contain toxins that are not good for health.
How to choose fresh and delicious celery
- Fresh celery has a bright green color and is clean, with thick leaf stems. The celery stalks should be round and even. There should be few roots, and the segments of the celery stalk should be long.
- Do not choose if you see the celery stalks are too large, as the white color may look appealing but has little aroma and a bland taste. Conversely, those with dark green color and many roots are old, tough, and should not be purchased.
