Corn to Boil
Always select young and tender corn for boiling, and drop into boiling water which has been a little salted; boil until done, which will require about twenty-five or thirty minutes. Some prefer it served on the cob, and it is also very nice cut off and seasoned with butter, pepper and salt.
A plain instruction from an era when field-ripe corn behaved very differently from what comes out of a supermarket bin. The timing is the one thing to ignore.
- The boiling timeTwenty-five to thirty minutes will reduce modern sweet corn to mush and leach out most of its sugar. Fresh supersweet or sugar-enhanced hybrids need 3 to 5 minutes in boiling water, and older or larger ears no more than 7.
- Why the original called for so longCorn of this period was largely open-pollinated field and sweet varieties whose sugars begin converting to starch soon after picking. A long boil was probably aimed at softening tough, starchy kernels rather than cooking tender ones.
- Salting the waterA little salt is fine; heavy salting is often said to toughen the kernel skins, though that is kitchen lore rather than settled fact. If you want seasoned corn, salt it on the plate with the butter.
- Selecting the ears"Young and tender" meant milk-stage corn: puncture a kernel and the liquid should be cloudy white, not clear (underripe) or pasty (overripe). Husks should be green and the silk moist at the base.
- Cutting off the cobFor the cut version, stand the cooked ear upright in a wide bowl and run a knife down the sides, then scrape the cob with the back of the blade to release the milky residue. That scraping carries much of the flavour.
- YieldReckon on two ears per person served on the cob, or roughly half to three quarters of a cup of cut kernels per ear.
Boiled green corn was a common marker of an American cookbook: European kitchens of the same period largely treated maize as animal feed or as meal for porridge, while American households ate it fresh from the ear in high summer. The insistence on "young and tender" reflects a practical limit rather than fussiness, since before refrigerated transport corn was best picked and eaten the same day, the crop being at its best in the brief milk stage. The modern habit of racing the corn from the field to the pot descends from that window, though the sugary hybrids developed over the twentieth century have made it much less urgent. Cutting the kernels off and dressing them with butter, pepper and salt anticipates what later cookbooks would sell as creamed or buttered corn.
