Remove the bracts, threads and the bottom of the stem from the corn cobs and rinse them.
Put the flasks in boiling water and add sugar and salt. Cook them over even heat and under a lid for approx. 10-15 minutes or until tender.
Pour the corn cobs for draining into a sieve.
Until the child can gnaw on the corn itself, the kernels can be scraped off with a knife after cooking. Frozen, thawed corn can also be served until the baby can gnaw off the flask. Give some fat on the corn to the baby.
