Does your mom like to experiment with food and tech? The Anova Precision Cooker makes sous vide cooking more accessible, making it a fun and easy way to try a new technique. Plus, Anova integrates with Amazon's Alexa and Google's Assistant.
If your mom is done making food for kids, the new Vitamix Ascent adds cool new smarts to the tried-and-true blender. This Vitamix knows which container you're using, and automatically adjusts the settings to get the best blend.
If your mom doesn't spend much time in the kitchen, a digital assistant might be a better option. The Amazon Tap is a smart speaker that docks to charge, but can be brought around the house for Alexa access or music.
If you want to give your mom an edge in the battle for the thermostat, try sending her a Nest Learning Thermostat. Then, every time Dad changes the temp, she can switch it back from her phone, without even getting off the couch.
