Cooking issue with cheap plastic forks
The plastic fork just melt (soften) a little bit, no biggie, you should be able to eat that.
You should buy cheap cutlery at the dollar store, you do not need many, maybe 4 sets (fork, spoon knife); when your exchange session is over, just leave them in your apartment; no need to bring them back with you.
Using real cutlery and washing them is better for the environment than using cheap plastic cutlery and throwing them in the trash (*)


(*) Unless you buy expensive biodegradable or compostable cutlery.
