Making a Grilled Vegetable Terrine using Agar..

[bmrodriguez10]

Should I dissolve the Agar Agar in Tomato Juice, or separately in water first?

You should dissolve the agar agar in hot water. Acidic elements, like tomato juice, degrade the gelling action of agar agar, so you may want to add tomato juice judiciously.
