General tips
Corn at 183°F for 30–40 min produces the sweetest, most tender kernels you have ever tasted. The sealed bag traps the natural sugars that normally evaporate in boiling water.
Add butter directly to the bag. It melts and bastes the corn continuously, infusing every kernel with rich flavor. A pinch of sugar enhances the natural sweetness.
Fresh corn is always better than frozen for sous vide. Frozen corn has already been blanched and will overcook in the bath, turning mushy.
For elote-style corn, sous vide first, then char on a grill or under the broiler for 2–3 min. The pre-cooked corn chars without drying out.
Anti-tip: do not cook corn for more than 45 min. Overcooked corn loses its snap and becomes starchy and soft. 30–40 min is the sweet spot for tender-crisp kernels.
Tender Sweet tips
Use the freshest corn you can find - it makes a huge difference
Save the butter from the bags for serving
Don't overcook - 30–40 min is perfect
For smoky flavor, char briefly on grill or under broiler after cooking
Traditional tips
This temperature works well for older, less sweet corn
The softer texture is more traditional
Great for cutting kernels off the cob after cooking
Very Soft tips
This temperature is best when you'll use the kernels in other dishes
Kernels cut very cleanly from the cob at this temperature
Not ideal if you want kernels with more bite
