gee i could just make this a regular series.
thanks to you guys who responded with tips earlier.
yesterday i make the recipe for "brownies cockaigne" from the Joy of Cooking. the edition is from about 1971 or 1972.
the recipe calls for a 9 x 13 inch pan, 4 eggs instead of 2, 1 cup of flour, 2 cups of sugar, and 4 oz. of chocolate. also called for nuts, but i left them out, as dh is allergic.
texture-wise, they were perfect. lovely, moist, and really chewy. but they were also very very sweet, and not as chocolatey as i'd have liked. i suppose i could add chocolate chips, but they might interfere with the texture.
might try dr._mama's again, but with the larger pan--they were wonderfully chocolatey. or might try altering the JoC one. not sure yet. will post results of next attempt, unless hospitalized.
