Dear Gavin

The black-grey film to which you refer is aluminium oxide and this is produced when the exposed surface of the aluminium bases are allowed to come into contact with any strong alkali, such as sodium hydroxide (caustic soda), which is the main active ingredient found in dishwasher detergents of all types. I imagine therefore that you have been washing this up in a dishwasher.

We would recommend hand washing this product using handwashing detergent which will not cause this problem.

To remove the current light deposits before changing to hand washing, use a little washing up liquid on the base and a little bit of elbow grease rubbing with a Scotchbrite green scouring pad or something similar. This will abrade the current aluminium oxide deposits and you will return to not having grey-streaked dishcloths etc. You can also use either of the AGA cleaning pastes if you have them and they will work even better. Once cleaned, rinse and dry off with a damp dishcloth and then place a drop of vegetable oil on the newly cleaned surfaces and wipe all over and then off using a piece of kitchen paper.

Dear Sarah,

Thank you for your question and we are really happy to hear that you love our roaster.
This range is so versatile and we can confirm that every piece in this range is freezer safe, apart from the glass lids.

Thank you for your query.

The dimensions of the cast aluminium roaster are the interior measurements.

The height with the lid on is 13cm, and with the lid inverted it is 10.5cm.

Kind regards

Dear John

This is the baby to consider:

http://www.agacookshop.co.uk/aga-cast-aluminium-rectangular-double-roaster.html

It is primarily sold to my mind for covered roasting in a conventional oven, keeping the oven itself from getting too dirty from splashes. As roasting strictly speaking is defined “cooking of food using radiant dry heat” (Larousse Gastronomique), such use is not really roasting at all, but baking, but that is not your concern. The Aga Roasting Oven does fulfil the requirement as it uses radiant heat as the primary means of transferring heat to the food being cooked and it is a dry environment, as steam is not contained (as with the covered roaster), but taken away by means of the oven venting system.

Where this utensil will hopefully score for you is used for roasting without its lid. Then it will continue to roast using radiant heat. The 6mm flat base can also be used on the Aga hotplates and makes excellent conduct when you want to finish the dish by making gravy or a sauce in the base, both when making the roux and when you whisk in the liquids.

The lid is also a ridged griddle and works on the Aga Boiling Plate to grill steaks, chops, cutlets and meatier cuts of fish such as tuna, marlin and swordfish. It is also good with chicken breasts for a chicken Caesar salad and for cooking liver, plus of course for griddling any vegetables: I use it for aubergine slices when making mousakka.

Its final use of course is as an excellent casserole: brown the meat in batches in the large base, placing each batch in turn when well browned in the upturned lid. Then continue with the alliums and so on and then return the resting ingredients to the base, add the remaining items and pour over the stock, wine or beer etc. Its base will come quickly to simmering point before you give a couple of minutes on the Simmering Plate. Cover and transfer to the Simmering Oven to cook “low and slow” for 2-4 hours, depending on the cut of meat.

The only drawback is that this utensil has to be used front to back in the ovens; it is not designed to hang from the oven runners like the normal Aga roasting tins. Nevertheless, I think it is perfect for what you have described.

I hope that helps.

If you require any further information, please do not hesitate to contact us again.

Assuring you of our best attention at all times.

Good morning Nigel

Thank you for your question.

Our cast aluminium cookware is suitable for all heat sources except induction and as this is cast aluminium, it should not cause any discolouration.

Kind regards

Dear Jane,

Thank you for your question.

We don't recommend dishwashing this range, to ensure you receive longevity from your pans.
The non-stick AGA cast aluminium range is so easy to clean, just a wipe with hot soapy water.

Best wishes,
AGA Cookshop

Good Morning Terry

Thank you for your question.

The roaster can be used on both the Simmering Plate and the Boiling Plate.

Kind regards
