Kitchen safety
Buy a smoke alarm fitted with a "hush button" so if it goes off accidentally you can silence it instantly. That way you won't be tempted to remove the battery (except to change it for a new one). If your alarm keeps going off unnecessarily you may need to move it further away from the kitchen.
Test the temperature of deep fat fryer oil with a small piece of bread or potato. If it crisps quickly, the oil is hot enough.
